Pellagra, a condition caused by a deficiency in vitamin B3, can be brought on by alcohol consumption as it hinders the absorption of the vitamin. In developed countries, alcoholism is the primary culprit behind cases of pellagra.

Pellagra: A Vitamin B3 Deficiency Disease

Pellagra is a disease caused by a lack of vitamin B3 (niacin) in the body. The name pellagra comes from the Italian words pelle agra, which means rough of sour skin. This disease is common in developing countries where corn is a major food source, of during prolonged disasters like famine of war. In developed countries, pellagra is rare because many foods are fortified with niacin. However, alcoholism is a common cause of pellagra in developed countries. Alcohol dependence can worsen pellagra by causing malnutrition, gastrointestinal problems, and B vitamin deficiencies. It can also inhibit the conversion of tryptophan to niacin and promote the accumulation of 5-ALA and porphyrins.

Pellagra affects a wide range of organs and tissues in the body, so its symptoms can vary. The classic symptoms of pellagra are known as the three Ds: diarrhea, dermatitis, and dementia. Niacin deficiency can cause dementia, depression, mania, and psychosis, which is called pellagra psychosis. The most noticeable symptom of pellagra is dermatitis, which is a hyperpigmented rash that appears on sun-exposed areas of the skin. This rash is usually symmetrical and bilateral, and it is often described as Casal’s necklace when it appears on the neck.

The Relative Risk Reduction (RRR) is calculated by subtracting the experimental event rate (EER) from the control event rate (CER), dividing the result by the CER, and then multiplying by 100 to get a percentage. In this case, the RRR is (35-20)÷35 = 0.4285 of 42.85%.

Amisulpride is the only option with documented evidence supporting its effectiveness as a clozapine augmentation treatment.

Clozapine is an effective antipsychotic drug used in the management of treatment-resistant schizophrenia (TRS). It was reintroduced in the 1990s with mandatory blood monitoring due to the risk of agranulocyte

If an individual experiences depression within a year of a relapse of schizophrenia, it should be classified as post-schizophrenic depression.

Understanding Post-Psychotic Depression

The term post-psychotic depression refers to three distinct groups of patients who experience depressive symptoms after an acute psychotic episode. The first group experiences depressive symptoms during the acute episode, which only become apparent as the positive psychotic symptoms resolve. The second group develops depressive symptoms as their positive psychotic symptoms resolve, while the third group experiences significant depressive symptoms after the acute episode has resolved.

The timing of the onset of depressive symptoms is not important for diagnostic purposes. The ICD 10 diagnostic guidelines for post-schizophrenic depression require that the patient has met general criteria for schizophrenia within the past 12 months, with some schizophrenic symptoms still present but no longer dominating the clinical picture. The depressive symptoms must be prominent and distressing, fulfilling at least the criteria for a depressive episode, and have been present for at least two weeks. While they are rarely severe enough to meet the criteria for a severe depressive episode, they can still be debilitating for the patient.

Antipsychotics: Minimum Effective Doses

The Maudsley Guidelines provide a table of minimum effective oral doses for antipsychotics in schizophrenia. The following doses are recommended for first episode and relapse (multi-episode) cases:

– Chlorpromazine: 200mg (first episode) and 300mg (relapse)
– Haloperidol: 2mg (first episode) and 4mg (relapse)
– Sulpiride: 400mg (first episode) and 800mg (relapse)
– Trifluoperazine: 10mg (first episode) and 15mg (relapse)
– Amisulpride: 300mg (first episode) and 400mg (relapse)
– Aripiprazole: 10mg (first episode and relapse)
– Olanzapine: 5mg (first episode) and 7.5mg (relapse)
– Quetiapine: 150mg (first episode) and 300mg (relapse)
– Risperidone: 2mg (first episode) and 4mg (relapse)

The minimum effective doses may vary depending on individual patient factors and response to treatment. It is important to consult with a healthcare professional before making any changes to medication dosages.

The onset of DTs typically happens between three to five days after stopping drinking. However, tremulousness of withdrawal convulsions (also known as rum fits) can occur during a drinking binge of shortly after stopping drinking. Alcoholic hallucinosis, on the other hand, can develop over a period of days of weeks and is characterized by auditory hallucinations. Unlike DTs, it is typically accompanied by less severe agitation and mental confusion.

Delirium is primarily characterized by a disturbance in consciousness, often accompanied by a widespread decline in cognitive abilities. Other common symptoms include changes in mood, perception, behavior, and motor function, such as tremors and nystagmus. This information is based on Kaplan and Sadock’s concise textbook of psychiatry, 10th edition, published in 2008.

Delirium (also known as acute confusional state) is a condition characterized by a sudden decline in consciousness and cognition, with a particular impairment in attention. It often involves perceptual disturbances, abnormal psychomotor activity, and sleep-wake cycle impairment. Delirium typically develops over a few days and has a fluctuating course. The causes of delirium are varied, ranging from metabolic disturbances to medications. It is important to differentiate delirium from dementia, as delirium has a brief onset, early disorientation, clouding of consciousness, fluctuating course, and early psychomotor changes. Delirium can be classified into three subtypes: hypoactive, hyperactive, and mixed. Patients with hyperactive delirium demonstrate restlessness, agitation, and hyper vigilance, while those with hypoactive delirium present with lethargy and sedation. Mixed delirium demonstrates both hyperactive and hypoactive features. The hypoactive form is most common in elderly patients and is often misdiagnosed as depression of dementia.

Familial Risk of Alzheimer’s Disease

The risk of developing Alzheimer’s disease is increased for first-degree relatives of patients who develop the disorder before the age of 85. This risk is three to four times higher than the risk for individuals without a family history of the disease. It is important for healthcare professionals to advise relatives of patients with Alzheimer’s disease about their increased genetic risk and provide appropriate support and resources.

Paroxetine Use During Pregnancy: Is it Safe?

Prescribing medication during pregnancy and breastfeeding is challenging due to the potential risks to the fetus of baby. No psychotropic medication has a UK marketing authorization specifically for pregnant of breastfeeding women. Women are encouraged to breastfeed unless they are taking carbamazepine, clozapine, of lithium. The risk of spontaneous major malformation is 2-3%, with drugs accounting for approximately 5% of all abnormalities. Valproate and carbamazepine are associated with an increased risk of neural tube defects, and lithium is associated with cardiac malformations. Benzodiazepines are associated with oral clefts and floppy baby syndrome. Antidepressants have been linked to preterm delivery and congenital malformation, but most findings have been inconsistent. TCAs have been used widely without apparent detriment to the fetus, but their use in the third trimester is known to produce neonatal withdrawal effects. Sertraline appears to result in the least placental exposure among SSRIs. MAOIs should be avoided in pregnancy due to a suspected increased risk of congenital malformations and hypertensive crisis. If a pregnant woman is stable on an antipsychotic and likely to relapse without medication, she should continue the antipsychotic. Depot antipsychotics should not be offered to pregnant of breastfeeding women unless they have a history of non-adherence with oral medication. The Maudsley Guidelines suggest specific drugs for use during pregnancy and breastfeeding. NICE CG192 recommends high-intensity psychological interventions for moderate to severe depression and anxiety disorders. Antipsychotics are recommended for pregnant women with mania of psychosis who are not taking psychotropic medication. Promethazine is recommended for insomnia.

Disruptive Behaviour of Dissocial Disorders

Conduct disorders are the most common reason for referral of young children to mental health services. These disorders are characterized by a repetitive and persistent pattern of antisocial, aggressive, of defiant conduct that goes beyond ordinary childish mischief of adolescent rebelliousness. Oppositional defiant disorder (ODD) shares some negative attributes but in a more limited fashion.

ICD-11 terms the disorder as ‘Conduct-dissocial disorder’, while DSM-5 recognizes three separate conditions related to emotional/behavioral problems seen in younger people: conduct disorder, oppositional defiant disorder, and intermittent explosive disorder. Conduct disorder is about poorly controlled behavior, intermittent explosive disorder is about poorly controlled emotions, and ODD is in between. Conduct disorders are further divided into childhood onset (before 10 years) and adolescent onset (10 years of older).

The behavior pattern of conduct disorders must be persistent and recurrent, including multiple incidents of aggression towards people of animals, destruction of property, deceitfulness of theft, and serious violations of rules. The pattern of behavior must result in significant impairment in personal, family, social, educational, occupational, of other important areas of functioning.

Oppositional defiant disorder represents a less severe form of conduct disorder, where there is an absence of more severe dissocial of aggressive acts. The behavior pattern of ODD includes persistent difficulty getting along with others, provocative, spiteful, of vindictive behavior, and extreme irritability of anger.

The prevalence of conduct disorders increases throughout childhood and is more common in boys than girls. The most frequent comorbid problem seen with conduct disorder is hyperactivity. The conversion rate from childhood conduct disorder to adult antisocial personality disorder varies from 40 to 70% depending on the study.

NICE recommends group parent-based training programs of parent and child training programs for children with complex needs for ages 3-11, child-focused programs for ages 9-14, and multimodal interventions with a family focus for ages 11-17. Medication is not recommended in routine practice, but risperidone can be used where other approaches fail and they are seriously aggressive.

Common Biases and Errors in Research

Reverse causality occurs when a risk factor appears to cause an illness, but in reality, it is a consequence of the illness. Information bias is a type of error that can occur in research. Two examples of information bias are observer bias and recall bias. Observer bias happens when the experimenter’s biases affect the study’s findings. Recall bias occurs when participants in the case and control groups have different levels of accuracy in their recollections.

There are two types of errors in research: Type I and Type II. A Type I error is when a true null hypothesis is incorrectly rejected, resulting in a false positive. A Type II error is when a false null hypothesis is not rejected, resulting in a false negative. It is essential to be aware of these biases and errors to ensure accurate and reliable research findings.

Marchiafava-Bignami Disease: A Rare Disorder Associated with Alcoholism and Malnutrition

Marchiafava-Bignami disease is a rare condition that is commonly observed in individuals with alcoholism and malnutrition. The disease is characterized by the progressive demyelination and subsequent necrosis of the corpus callosum, which can lead to a range of nonspecific clinical symptoms such as motor of cognitive disturbances. The course of the disease can be either acute of chronic, and patients may experience dementia, spasticity, dysarthria, and an inability to walk. The outcome of the disease is unpredictable, with some patients lapsing into a coma and dying, while others may survive for many years in a demented state, of even recover.

Munchausen’s syndrome by proxy, also known as fabricated or induced illness, is a rare form of child abuse where a caregiver, usually the mother, falsifies illness in a child by fabricating of producing symptoms and presenting the child for medical care while denying knowledge of the cause. It is most commonly seen in children under the age of 4, with symptoms including apnoea, anorexia, feeding problems, and seizures. The disorder is now recognized as ‘Factitious Disorder Imposed on Another’ in the DSM-5, with criteria including falsification of physical of psychological signs of symptoms, presentation of the victim as ill, and evident deceptive behavior. The perpetrator, not the victim, receives this diagnosis. Presenting signs of symptoms can take the form of covert injury, fabrication of symptoms, of exaggeration of existing symptoms. Symptoms are often subjective and easy to fake.

Individuals who have experienced four of more mood swings within a 12 month period must demonstrate a period of stability lasting at least 6 months before resuming driving. For those who have experienced hypomania of mania, a period of stability lasting 3 months is required before returning to driving, which is extended to 6 months if there have been repeated mood changes over a 12 month period. Similarly, individuals with psychosis must also demonstrate a period of stability lasting 3 months before resuming driving. However, HGV drivers who have experienced mania/hypomania of psychosis must demonstrate a longer period of stability lasting 3 years (36 months) before returning to driving.

A key objective in the treatment of anorexia nervosa is to assist individuals in achieving a healthy body weight of BMI appropriate for their age. It is not recommended to rely solely on screening tools like SCOFF to diagnose eating disorders. While eating disorders can occur at any age, it is important to note that the risk is greatest for adolescents between the ages of 13 and 17, particularly young men and women. It is not advisable to use a single metric such as BMI of duration of illness to determine whether treatment for an eating disorder is necessary.

Eating Disorders: NICE Guidelines

Anorexia:
For adults with anorexia nervosa, consider individual eating-disorder-focused cognitive behavioural therapy (CBT-ED), Maudsley Anorexia Nervosa Treatment for Adults (MANTRA), of specialist supportive clinical management (SSCM). If these are not acceptable, contraindicated, of ineffective, consider eating-disorder-focused focal psychodynamic therapy (FPT). For children and young people, consider anorexia-nervosa-focused family therapy (FT-AN) of individual CBT-ED. Do not offer medication as the sole treatment.

Bulimia:
For adults, the first step is an evidence-based self-help programme. If this is not effective, consider individual CBT-ED. For children and young people, offer bulimia-nervosa-focused family therapy (FT-BN) of individual CBT-ED. Do not offer medication as the sole treatment.

Binge Eating Disorder:
The first step is a guided self-help programme. If this is not effective, offer group of individual CBT-ED. For children and young people, offer the same treatments recommended for adults. Do not offer medication as the sole treatment.

Advice for those with eating disorders:
Encourage people with an eating disorder who are vomiting to avoid brushing teeth immediately after vomiting, rinse with non-acid mouthwash, and avoid highly acidic foods and drinks. Advise against misusing laxatives of diuretics and excessive exercise.

Additional points:
Do not offer physical therapy as part of treatment. Consider bone mineral density scans after 1 year of underweight in children and young people, of 2 years in adults. Do not routinely offer oral of transdermal oestrogen therapy to treat low bone mineral density in children of young people with anorexia nervosa. Consider transdermal 17-β-estradiol of bisphosphonates for women with anorexia nervosa.

Note: These guidelines are taken from NICE guidelines 2017.

Probable alcoholic hallucinosis is indicated when non-persecutory second person auditory hallucinations are present in an individual who chronically abuses alcohol. Antipsychotics are effective in treating these hallucinations, but only if the individual abstains from alcohol.

There are various treatment options available for PTSD, including the use of selective serotonin reuptake inhibitors (SSRIs) and venlafaxine.

Stress disorders, such as Post Traumatic Stress Disorder (PTSD), are emotional reactions to traumatic events. The diagnosis of PTSD requires exposure to an extremely threatening of horrific event, followed by the development of a characteristic syndrome lasting for at least several weeks, consisting of re-experiencing the traumatic event, deliberate avoidance of reminders likely to produce re-experiencing, and persistent perceptions of heightened current threat. Additional clinical features may include general dysphoria, dissociative symptoms, somatic complaints, suicidal ideation and behaviour, social withdrawal, excessive alcohol of drug use, anxiety symptoms, and obsessions of compulsions. The emotional experience of individuals with PTSD commonly includes anger, shame, sadness, humiliation, of guilt. The onset of PTSD symptoms can occur at any time during the lifespan following exposure to a traumatic event, and the symptoms and course of PTSD can vary significantly over time and individuals. Key differentials include acute stress reaction, adjustment disorder, and complex PTSD. Management of PTSD includes trauma-focused cognitive behavioral therapy (CBT), eye movement desensitization and reprocessing (EMDR), and supported trauma-focused computerized CBT interventions. Drug treatments, including benzodiazepines, are not recommended for the prevention of treatment of PTSD in adults, but venlafaxine of a selective serotonin reuptake inhibitor (SSRI) may be considered for adults with a diagnosis of PTSD if the person has a preference for drug treatment. Antipsychotics such as risperidone may be considered in addition if disabling symptoms and behaviors are present and have not responded to other treatments. Psychological debriefing is not recommended for the prevention of treatment of PTSD. For children and young people, individual trauma-focused CBT interventions of EMDR may be considered, but drug treatments are not recommended.

Psychiatric Issues in the Postpartum Period

The period following childbirth, known as the postpartum period, can be a time of significant psychiatric challenges for women. Many women experience a temporary mood disturbance called baby blues, which is characterized by emotional instability, sadness, and tearfulness. This condition typically resolves within two weeks.

However, a minority of women (10-15%) experience postpartum depression, which is similar to major depression in its clinical presentation. In contrast, a very small number of women (1-2 per 1000) experience postpartum psychosis, also known as puerperal psychosis. This is a severe form of psychosis that occurs in the weeks following childbirth.

Research suggests that there may be a link between puerperal psychosis and mood disorders, as approximately 50% of women who develop the condition have a family history of mood disorder. Puerperal psychosis typically begins within the first two weeks following delivery. It is important for healthcare providers to be aware of these potential psychiatric issues and to provide appropriate support and treatment to women during the postpartum period.
