Mannerisms and stereotypies in catatonia: beyond simple motor movements.

Background: Catatonia is a complex syndrome with prominent psychomotor, cognitive, and affective manifestations. Among the commonly described manifestations of catatonia are mannerisms and stereotypies. Kahlbaum, who coined the term catatonia, described several presentations of mannerisms and stereotypies as complex behaviors in his monograph.

Assessing the risk of COVID-19 reinfection and severe outcomes among individuals with substance use disorders: a retrospective study using real-world electronic health records.

Objective: Despite advancement in vaccines and treatments for COVID-19 over the past 2 years, many concerns remain about reinfection and waning immunity against COVID-19 and its variants, especially among people with substance use disorder (SUD). The study assessed the risk of COVID-19 reinfection and severe illness among adults with SUD and their vaccination status to inform management in this vulnerable population as the pandemic continues.

Design: Retrospective cohort study.

Do prescription stimulants increase risk of Parkinson's disease among adults with attention-deficit hyperactivity disorder? A retrospective cohort study.

Background: Parkinson's disease (PD) is a common neurodegenerative disorder in older adults that is associated with neuroinflammation, oxidative stress, and characterized by loss of dopaminergic cells. Illicit stimulants increase oxidative stress and are associated with increased risk of PD. Prescription stimulants are similar in mechanism to illicit stimulants, yet their influence on PD is not well described.

[Capacitive requirement for acute in-patient care of patients with psychosomatic diseases in bavaria].

Estimations of the requirement for acute in-patient care of patients with psychosomatic diseases in Bavaria have to rely on respective data on their incidence and prevalence as valid requirement data are missing. The required capacity of in-patient beds depends on several, inconsistently figured parameters: hospitalization rate, length of stay, occupancy rate. Based on conservative assumptions the hospitalization rate was calculated to be at least 1.

Signal-averaged P wave: predictor of atrial fibrillation.

Abnormalities of the P wave seen during sinus rhythm are associated with atrial fibrillation and other supraventricular arrhythmias. Intra-atrial conduction delays can be seen on the surface ECG as P wave prolongation, which is more visible with averaging techniques used in advanced recording devices. Averaging followed by amplification after proper filtering of the electrical signal should allow more precise measurements of duration and amplitude of the P wave.

Neuroleptic malignant syndrome: observations on altered consciousness.

A young man with a previously untreated schizophrenia developed a neuroleptic malignant syndrome (NMS) on the second day of neuroleptic treatment. The dominant symptom was deep coma. The NMS occurred on the second day of neuroleptic therapy with rapidly progressing mental deterioration, temperature elevation, and extrapyramidal signs.

[Five years experience with an influenza subunit vaccine (author's transl)].

After a short review on development, production, and assay of influenza vaccines the authors discuss the special properties of influenza virus subunit vaccine which contains the purified protective antigens of the influenza virus. The results of pre-clinical and clinical studies allow the conclusion that subunit vaccine is better tolerated than and at least as potent as conventional influenza vaccines. It therefore seems to be especially suited for annual re-vaccinations of persons at high risk.

[The Kleine-Levin-Critchley-syndrome. A contribution to the solution of differential diagnosis (author's transl)].

The typical symptoms of the so-called Kleine-Levin-Critchley-Syndrome are described according to our own observation of four selected patients (one woman, three men) on the background of the literature on the subject. In contrast to the first descriptions we characterise this syndrome by the Trias: periodic hypersomnia, vegetative disturbances (especially of food intake) and psychopathologic symptoms. Especially young men in their second decade of life suffer from this syndrome.

[Immunisation against influenza with a new subunit vaccine tested on children at risk (author's transl)].

The efficacy and tolerance of Sandovac, a new subunit vaccine, was tested in 104 children and juveniles aged 2 1/4 to 17 years, at five children's clinics. Sandovac 1000 was given to 39 children, Sandovac 2000 to 65. The vaccine was well tolerated, no appreciable side effects--local or systemic--having been recorded.

[Comparison of the effects of the anthracene derivative danitracen (WA335-BS) and amitriptyline in depressive patients (author's transl)].

9,10-Dihydro-10-(1-methyl-4-piperidylidene)-9-anthrol (danitracen, WA 335) is a substance with a stronger peripheral and partly central antiserotonin and antihistamine effect than cyproheptadine. In 5 different hospitals, WA 335 (3 X 1 mg/die) was investigated versus amitriptyline (3 X 50 mg/die) in a double-blind study in 116 depressive patients of different nosology. In the end of the investigation period (20 days), under WA 335 treatment 67.
