Consultation-Liaison Case Conference: Overcoming Bias in the Differential Diagnosis of Psychosis.

We present the case of a 34-year-old Black patient with no significant psychiatric history who presented with catatonia and psychotic symptoms following a recent severe acute respiratory syndrome coronavirus-2 infection, whose diagnosis of coronavirus disease 2019 encephalitis was delayed by premature attribution of his symptoms to a primary psychiatric etiology. Top experts in the consultation-liaison field provide guidance for this commonly encountered clinical case based on their experience and a review of the available literature. Key teaching topics include the diagnosis and management of coronavirus disease 2019 encephalitis, cognitive bias, and racial bias. Specifically, this case illustrates the role of the consultation-liaison psychiatrist in identifying medical conditions that may overlap with psychiatric presentations and in advocating for marginalized patients.

A practical guide for buprenorphine initiation in the primary care setting.

Buprenorphine is a safe and effective treatment for opioid use disorder but remains underutilized because a major challenge of conventional buprenorphine initiation (termed induction) is that the patient must already be in opioid withdrawal. Previous legal barriers and clinician lack of familiarity with the unique pharmacology of buprenorphine have also limited its use. In this review, we outline changes regarding buprenorphine prescribing laws and physician perceptions of buprenorphine. We also review buprenorphine pharmacology and novel low-dose buprenorphine induction procedures that can be adopted in primary care settings to improve treatment acceptability, retention, and outcomes.

Incontinence as a catatonic sign.

BACKGROUND: Incontinence (urinary or fecal) is not included in DSM-5 criteria for catatonia or in most catatonia rating scales. However, there is a historical basis for the inclusion or consideration of incontinence as a catatonic sign. METHODS: We performed a review of the literature and found references to urinary disturbances and fecal incontinence in 19th- and 20th-century literature. We did a computerized literature review using the terms "catatonia," "catatonic," and "incontinence." RESULTS: We highlight 2 cases in which urinary or fecal incontinence was a presenting or predominant feature of catatonia. Clinical improvement was associated with improvement in incontinence. CONCLUSIONS: These preliminary findings suggest that urinary and fecal incontinence may be an uncommon presentation of catatonia. Furthermore, incontinence may improve at the same time catatonia improves with treatment. The neural circuitry that controls micturition and the sphincter involves neural pathways and multiple neurotransmitters. Catatonia can cause a reemergence of involuntary or reflex maturation, leading to urinary incontinence. This may lead to the need for additional custodial care for patients. Thus, the detection and monitoring of urinary and fecal incontinence may help us better understand the pathophysiology and impairment associated with catatonia.

Discontinuing antidepressants: Pearls and pitfalls.

Stopping antidepressants can be challenging due to the high rate of discontinuation symptoms. Patients with antidepressant discontinuation syndrome (ADS) commonly experience insomnia, flu-like symptoms, mood disturbances, dizziness, and paresthesias, but a broad array of adverse effects is possible. Symptoms can last for days to months, and different symptoms have different durations. Patient education, identification of patients most at risk for developing symptoms, and a slow antidepressant taper or cross-taper are important steps in mitigating the risk of ADS and managing patient concerns about ADS. Tapers should be carried out over weeks to months. Discontinuation symptoms should be managed with restarting the prior dose of antidepressant and then tapering even more slowly, with additional symptomatic management as needed.

Periodic Catatonia Marked by Hypercortisolemia and Exacerbated by the Menses: A Case Report and Literature Review.

Kahlbaum first described catatonia; later Kraepelin, Gjessing, and Leonhard each defined periodic catatonia differently. A 48-year-old female with catatonia, whose grandmother probably died from it, was prospectively followed for >4 years in a US psychiatric state hospital. Through 4 catatonic episodes (one lasting 17 months) there were menstrual exacerbations of catatonia and increases in 4 biological variables: (1) creatine kinase (CK) up to 4,920 U/L, (2) lactate dehydrogenase (LDH) up to 424 U/L, (3) late afternoon cortisol levels up to 28.0 mcg/dL, and (4) white blood cell (WBC) counts up to 24,200/mm3 with neutrophilia without infections. Records from 17 prior admissions documented elevations of WBC and LDH and included an abnormal dexamethasone suppression test (DST) which normalized with electroconvulsive therapy. Two later admissions showed CK and WBC elevations. We propose that these abnormalities reflect different aspects of catatonic biology: (1) the serum CK, the severity of muscle damage probably exacerbated by the menses; (2) the hypercortisolemia, the associated fear; (3) the leukocytosis with neutrophilia, the hypercortisolemia; and (4) the LDH elevations, which appear to be influenced by other biological abnormalities. Twentieth-century literature was reviewed for (1) menstrual exacerbations of catatonia, (2) biological abnormalities related to periodic catatonia, and (3) familial periodic catatonia.

The Incidence of Psychiatric Medication Use and Its Effect on Intraoperative Bleeding in Facial Cosmetic Patients.

PURPOSE: Psychiatric medications, particularly the selective serotonin reuptake inhibitors, have been associated with increased surgical bleeding. This study aims to compare intraoperative surgical bleeding between cosmetic surgery patients who are and are not taking psychiatric medications. METHODS: The charts of 392 consecutive patients who underwent cosmetic facial surgery at the senior author's practice were reviewed. Independent variables included self-reported psychiatric history, psychiatric diagnoses, and psychiatric medications as documented in the preoperative history and physical examination. The primary endpoint was administration of desmopressin (DDAVP), our proxy for increased surgical bleeding. Significant predictors of these endpoints were determined via Chi-squared testing. RESULTS: One hundred and seventeen patients had a psychiatric diagnosis (30%), and 129 patients were taking some class of psychiatric medication (33%). Seventy-two patients received DDAVP (18%). A psychiatric diagnosis did not predict DDAVP administration (14.3% for patients with a psychiatric diagnosis vs. 20.88% for those without, p = 0.14). The use of a psychiatric medication was not associated with DDAVP administration (14.7 vs. 21%, p = 0.14). Male gender significantly predicted DDAVP administration (27.8 vs. 16.9% for females, p = 0.04). CONCLUSION: The use of psychiatric medications does not predict increased intraoperative surgical bleeding. This is useful given the prevalence of psychiatric medication use among this patient population and obviates the need for discontinuation of these medications, which otherwise could be consequential.

Perioperative antibiotic use in diabetic patients: A retrospective review of 670 surgeries.

PURPOSE: Carpal tunnel syndrome (CTS) has a high incidence in diabetic patients, with a reported incidence up to 21%. In severe cases of CTS, patients may undergo carpal tunnel release (CTR) surgery, which involves the risk of infection and other complications. To decrease the risk of infection, some physicians provide prophylactic antibiotics. Our study examines the effects of prophylactic antibiotic use, especially in a high-risk, diabetic population. METHODS: A total of 469 CTR surgeries performed by plastic surgery specialists were reviewed for diabetic status at the time of surgery and perioperative antibiotic use. Postoperative infections occurring at the surgical site were recorded. Associations between perioperative antibiotic use and infection in diabetics and nondiabetics were then analyzed. RESULTS: No significant decrease in infection rate was seen in those who were given perioperative antibiotic use. This relationship held true for diabetics as well. CONCLUSIONS: No benefit of antibiotic use during CTR surgery was seen. There was, however, a trend toward a protective effect in patients with uncontrolled diabetes mellitus, suggesting that such patients may benefit from perioperative antibiotic use. LEVEL OF EVIDENCE: III (Retrospective cohort study), Therapeutic.

The Impact of Age Upon Healing: Absolute Quantification of Osteogenic Genes in Calvarial Critical-Sized Defects.

BACKGROUND: The current study was performed to elucidate changes in growth factor expression over time in critical-sized calvarial defects in rats from infancy to skeletal maturity. MATERIALS AND METHODS: Critical-sized parietal defects of 5, 6, and 8 mm were created in postnatal day 6 (P6), postnatal day (P20), and postnatal day (P84) adult rats, respectively. Dura was harvested at 3, 7, or 14 days after surgery, and serial micro-computed tomography imaging was performed through 12 weeks postoperatively. Absolute quantitative polymerase chain reaction was performed for Bone Morphogenic Protein-2 (BMP-2), Fibroblast Growth Factor-2 (FGF-2), Insulin-like Growth Factor-1 (IGF-1), and Transforming Growth Factor-ß1 (TGF-ß). RESULTS: The P6 (6-d-old) rats showed the greatest difference in gene expression between the dura derived from the defect side and the dura derived from the control side, demonstrating significant differences in TGF-ß1, BMP-2, IGF-1, and FGF-2 at various time intervals. Absolute gene expression in the defect dura was highest in the P6 rats and declined with age. Significant differences were noted at limited time points in the P20 rats for TGF-ß1 and BMP-2 as well as in the P84 rats for TGF-ß1. TGF-ß1 was the only gene studied that showed significant differences at postoperative days 3, 7, and 14 in varying age groups. CONCLUSIONS: The P6 rats have a higher osteogenic potential accompanied by a more vigorous alteration in growth factor expression compared with the P20 or P84 rats. Decrease in BMP-2 and FGF-2 as well as relative increase in TGFß-1 messenger RNA were observed in healing defects. These data provide valuable insight into the mechanism of healing of critical-sized defects and may be of use to engineer factor-releasing implants to correct skull defects.

Environmental factors that contribute to upper eyelid ptosis: a study of identical twins.

BACKGROUND: Current literature provides little information about the impact of environmental exposures on the severity of acquired blepharoptosis. OBJECTIVE: The authors assessed environmental factors that may contribute to eyelid ptosis in a population of identical twins. METHODS: Photographs of 286 sets of twins from a prospectively collected database from 2008 to 2010 were reviewed. The authors identified 96 sets of identical twins (192 individual persons) who had differing severity of ptosis. Digital photographs were analyzed, and the degree of ptosis was measured in each eye of every subject. The external factors that could potentially contribute to blepharoptosis were taken into consideration. The authors then assessed the correlations of 9 different environmental risk factors with ptosis. Generalized linear mixed model were constructed to determine the associations of ptosis measurements with environmental risk factors obtained from the subject survey database. RESULTS: The mean level of upper eyelid ptosis in the study population was 1.1 mm. The mean difference in ptosis between twins was 0.5 mm. Wearing contact lenses, either hard or soft, was significantly associated with ptosis. The mean ptosis measurement among twins who did not wear contact lenses was 1.0 mm; for those who wore soft contact lenses, the mean was 1.41 mm, and for those who wore hard contact lenses, the mean was 1.84 mm. CONCLUSIONS: Acquired ptosis is not linked to body mass index, smoking behavior, sun exposure, alcohol use, work stress, or sleep. Wearing either hard or soft lenses was associated with an increased risk of ptosis. These influences are independent of genetic predisposition. LEVEL OF EVIDENCE: 3 Diagnostic.

The effect of preoperative migraine headache frequency on surgical outcomes.

BACKGROUND: The Global Burden of Disease ranks migraine headache among the most disabling of conditions, and in the United States, migraine headache is one of the top five causes of visits to the emergency room. As migraineurs turn to surgical treatment for relief, it is unknown how migraine frequency influences outcomes. METHODS: In total, 488 patients prospectively completed the migraine headache questionnaires preoperatively and at least 11 months postoperatively. Patients were grouped into three cohorts based on migraine frequency of one to 14 per month (episodic), 15 to 29 per month (chronic), or at least daily (daily). Statistics were performed with paired t tests, linear regression, and analysis of variance with Tukey's honestly significant difference test. RESULTS: All groups experienced a significant benefit from surgery in terms of frequency, duration, and severity of migraine headache, and Migraine Headache Index. Patients experienced significantly different final outcomes based on their frequency cohort with respect to duration (p = 0.02), frequency (p < 0.0001), and Migraine Headache Index (p < 0.0001). However, when the preoperative score is controlled for, the only significant difference between cohorts occurred in Migraine Headache Index among daily migraineurs compared with episodic (p = 0.0003) and chronic (p = 0.0008) migraineurs. No other significant findings persisted. CONCLUSIONS: All cohorts, regardless of their frequency of migraine headache, achieved significant improvement in frequency, duration, severity, and Migraine Headache Index. The groups also achieved statistically different final outcomes, but no group benefits more than the other when improvement is quantified, and patients can expect similar relative improvement.

Augmentation of intraorbital volume with fat injection.

BACKGROUND: Enophthalmos is a challenging surgical problem to correct. Standard techniques to adjust orbital volume require invasive maneuvers such as osteotomies. Fat injection may provide a simple and less-invasive way of augmenting orbital volume to correct enophthalmos. METHODS: The right eye orbital volume of 10 New Zealand White rabbits was augmented with fat. Autologous fat was diced and injected into the retrobulbar space. Computed tomographic scans were evaluated for changes in globe position and retrobulbar volume. Visually evoked potentials were conducted to test the integrity of the optic tract. Rabbits were killed at 12 weeks after surgery. Orbital exenterations were performed to allow for gross and histologic evaluation. RESULTS: Right globe position showed a mean increase in eye proptosis of 3.4 mm at postoperative day 1 and 0.9 mm at 11 weeks postoperatively in comparison with the left globe position. No significant change was noted in the left globe position. Retrobulbar volume demonstrated an initial mean increase of 31 percent and a final mean increase of 9.8 percent at 11 weeks in the right eye compared with the left eye. Visually evoked potentials revealed intact optic pathways in all animals. Gross anatomical evaluation showed deposition of fat grafts. Histologic analysis showed both revascularized and necrotic areas of fat. No retinal or optic nerve damage was identified. CONCLUSIONS: Fat injection can augment orbital volume in an animal model and preserve visual function. Further investigation is necessary to document the clinical safety and value of this technique in humans.

An anatomical study of the lesser occipital nerve and its potential compression points: implications for surgical treatment of migraine headaches.

BACKGROUND: This study maps the course of the lesser occipital nerve and its potential compression sites in the posterior scalp. METHODS: Twenty sides of 10 fresh cadaveric heads were dissected. Two fixed anatomical landmarks were used: the y axis was the vertical midline in the posterior scalp through the midline of the cervical spine. The x axis was a horizontal line drawn between the most anterosuperior points of the external auditory meatus. A topographic map of the lesser occipital nerve and its potential compression points was created. RESULTS: The lesser occipital nerve emerged from the posterior border of the sternocleidomastoid muscle at an average of 6.4 ± 1.4 cm lateral to the y axis and 7.5 ± 0.9 cm caudal to the x axis. Branches of the occipital artery were found to interact with the lesser occipital nerve in 11 of the 20 hemiheads (55 percent). The mean location of the artery-nerve interaction was 5.1 ± 0.9 cm lateral to the y axis and 2 ± 1.45 cm caudal to the x axis. Two patterns of artery-nerve interaction were seen: a single site of artery crossing over the nerve in nine of 20 hemiheads (45 percent) and a helical intertwining relationship in two of 20 of hemiheads (10 percent). A fascial band was identified to compress the lesser occipital nerve in four of 20 hemiheads (20 percent). CONCLUSION: This anatomical study traced the lesser occipital nerve as it courses through the posterior scalp and mapped its potential decompression sites.

The incidence of vitamin, mineral, herbal, and other supplement use in facial cosmetic patients.

BACKGROUND: Dietary supplement use is common in the United States. Some herbal supplements may cause coagulopathy, hypertension, or dry eyes. The goal of this study is to reveal the incidence of herbal supplement use in the cosmetic surgery population. METHODS: A retrospective chart review of 200 patients undergoing facial cosmetic surgery performed by a single surgeon was performed. Variables studied included patient age, sex, surgical procedure, herbal medication use, and intraoperative variables. Exclusion criteria were age younger than 15 years, noncosmetic procedures such as trauma, and incomplete preoperative medication form. Patients were subdivided into the supplement user group (herbal) and the supplement nonuser group (nonherbal). Statistical analysis included descriptive statistics, t test, and chi-square analysis. RESULTS: The incidence of supplement use was 49 percent in the 200 patients; 24.5 percent of patients used only vitamins or minerals, 2.5 percent of patients used only animal- and plant-based (nonvitamin/mineral) supplements, and 22 percent of patients used both types of supplements. In the herbal group, patients used an average of 2.8 supplements. The herbal and nonherbal groups differed significantly in sex (herbal, 89.8 percent female; nonherbal, 77.5 percent; p < 0.04) and age (herbal, 51.4 years; nonherbal, 38.5 years; p < 0.001). CONCLUSIONS: Herbal supplement use is prevalent in the facial cosmetic surgery population, especially in the older female population. Considering the potential ill effects of these products on surgery and recovery, awareness and careful documentation and prohibiting the patients from the consumption of these products will increase the safety and reduce the recovery following cosmetic procedures.

Frequency of the preoperative flaws and commonly required maneuvers to correct them: a guide to reducing the revision rhinoplasty rate.

BACKGROUND: The purpose of this study was to identify the most common deformities seen preoperatively in secondary rhinoplasty patients and the required surgical maneuvers to correct them. METHODS: A retrospective chart review of 100 consecutive secondary rhinoplasty patients was performed. Preoperative variables included demographics, prior rhinoplasty data, main aesthetic/functional concerns, and the senior author's physical examination of the nose. Details of the operative maneuvers were reviewed. RESULTS: The average patient age was 39.2 years. All patients had previous rhinoplasties performed by other surgeons. The most common preoperative complaints were airway occlusion (65 percent), dorsum asymmetry (33 percent), nostril asymmetry (18 percent), and tip asymmetry (14 percent). The most common preoperative nasal deformities seen by the senior author (B.G.) were dorsal asymmetry (65 percent), wide dorsum (47 percent), nostril asymmetry (41 percent), wide alar base (38 percent), and dorsal hump (30 percent). The senior author saw significantly more nasal deformities than the patients themselves, especially in the following areas: dorsal asymmetry (65 percent versus 33 percent; p = 0.0002), wide dorsum (47 percent versus 13 percent; p < 0.0001), nostril asymmetry (41 percent versus 18 percent; p = 0.0003), wide alar base (38 percent versus 6 percent; p < 0.0001), dorsal hump (30 percent versus 9 percent; p < 0.0001), and columella protrusion (25 percent versus 6 percent; p = 0.0002). The most common revision rhinoplasty surgical maneuvers were septoplasty (71 percent), alar rim graft (67 percent), dorsal graft (63 percent), osteotomy (60 percent), and dorsal hump removal (46 percent). CONCLUSIONS: The high incidence of airway concerns among secondary rhinoplasty patients is alarming and emphasizes the urgent need to pay attention to the airway during primary rhinoplasty. There is often a disparity between what the patient sees and what the surgeon observes.

The auriculotemporal nerve in etiology of migraine headaches: compression points and anatomical variations.

BACKGROUND: The auriculotemporal nerve has been identified as one of the peripheral trigger sites for migraine headaches. However, its distal course is poorly mapped following emergence from the parotid gland. In addition, a reliable anatomical landmark for locating the potential compression points along the course of the nerve during surgery has not been sufficiently described. METHODS: Twenty hemifaces on 10 fresh cadavers were dissected to trace the course of the auriculotemporal nerve from the inferior border of the zygomatic arch to its termination in the temporal scalp. The compression points were mapped and the distances were measured from the most anterosuperior point of the external auditory meatus, which was used as a fixed anatomical landmark. RESULTS: Three potential compression points along the course of the auriculotemporal nerve were identified. Compression points 1 and 2 corresponded to preauricular fascial bands. Compression point 1 was centered 13.1±5.9 mm anterior and 5.0±7.0 mm superior to the most anterosuperior point of the external auditory meatus, whereas compression point 2 was centered at 11.9±6.0 mm anterior and 17.2±10.4 mm superior to the most anterosuperior point of the external auditory meatus. A significant relationship was found between the auriculotemporal nerve and superficial temporal artery (compression point 3) in 80 percent of hemifaces, with three patterns of interaction: a single site of artery crossing over the nerve (62.5 percent), a helical intertwining relationship (18.8 percent), and nerve crossing over the artery (18.8 percent). CONCLUSION: Findings from this cadaver study provide information relevant to the operative localization of potential compression points along the auriculotemporal nerve.
