|Title||Psychotic mania in glucose-6-phosphate-dehydrogenase-deficient subjects.|
|Abstract||BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD) deficiency has been associated with acute psychosis, catatonic schizophrenia, and bipolar disorders by previous inconclusive reports. A particularly disproportionate rate of enzyme deficiency was found in manic schizoaffective patients from 662 lithium patients surveyed in Sardinia. The purpose of this study was to describe clinical characteristics which may be potentially associated with G6PD deficiency. METHODS: Characteristics of episodes, course of illness, family pattern of illness, laboratory tests, and treatment response of 29 G6PD-deficient subjects with a Research Diagnostic Criteria diagnosis of manic schizoaffective disorder were abstracted from available records. RESULTS: The most peculiar pattern was that of acute recurrent psychotic manic episodes, mostly characterized by loosening of associations, agitation, catatonic symptoms, and/or transient confusion, concurrent hyperbilirubinemia, positive psychiatric family history, and partial response to long-term lithium treatment. CONCLUSIONS: A relationship between psychiatric disorder and G6PD deficiency is to be searched in the bipolar spectrum, particularly among patients with a history of acute episodes with psychotic and/or catatonic symptoms or with transient confusion.|

|Title||Glucose-6 phosphate dehydrogenase deficiency and psychotic illness.|
|Abstract||Mr. T, a 28-year-old unmarried male, a diagnosed case of Glucose-6 Phosphate Dehydrogenase (G6PD) deficiency since childhood, presented with 13 years of psychotic illness and disturbed biological functions. He showed poor response to antipsychotics and mood stabilizers and had three prior admissions to Psychiatry. There was a family history of psychotic illness. The General Physical Examination and Systemic Examination were unremarkable. Mental Status Examination revealed increased psychomotor activity, pressure of speech, euphoric affect, prolixity, delusion of persecution, delusion of grandiosity, delusion of control, thought withdrawal and thought insertion, and second and third person auditory hallucinations, with impaired judgment and insight. A diagnosis of schizophrenia paranoid type, with a differential diagnosis of schizoaffective disorder manic subtype, was made. This case is being reported for its rarity and atypicality of clinical presentation, as well as a course of psychotic illness in the G6PD Deficiency state,with its implications on management.|

|Title||Acute anterior compartment syndrome associated with psychogenic polydipsia.|
|Abstract||The aim of this paper is to describe the association of psychogenic polydipsia with anterior compartment syndrome.|
A 31-year-old man with glucose-6-phosphate-dehydrogenase (G6PD) deficiency had a history of paranoid schizophrenia from age 16 complicated by the use of drugs. Four years after the initial diagnosis of schizophrenia, he developed psychogenic polydipsia. This was complicated by episodic severe acute hyponatraemia with seizures and, on one occasion, by generalized rhabdomyolysis. One episode of severe acute hyponatraemia with delirium led to anterior compartment syndrome in both legs. Delayed diagnosis and treatment led to extensive myonecrosis and permanent bilateral foot drop. For 6 years his polydipsia remained partially controlled in a locked psychiatric ward with limited leave, until his sudden death related to severe water intoxication.
Anterior compartment syndrome is a rare event associated with psychogenic polydipsia. Psychiatrists, physicians and surgeons should be aware of the seriousness of anterior compartment syndrome and its potential to increase morbidity in patients with psychogenic polydipsia.

|Title||Epidemiology and Associated Morbidity of Pterygium: A Large, Community-Based Case-Control Study.|
|Abstract||To evaluate the prevalence and risk factors of various conditions among patients with pterygium.|
A retrospective observational case control study of 4,037 patients who were diagnosed with pterygium in the Central District of Clalit Health Services in Israel from 2000-2009. A total of 16,054 randomly selected controls from the district HMO members. Personal, medical, and demographic information were extracted from patients' files. We calculated the prevalence of various ocular, systemic, and demographic conditions as risk factors for pterygium.
The average age of pterygium patients was 58.4?±?14 years; 56.9% were male. A significant tendency to develop pterygium was found among individuals of lower socioeconomic status (p?0.001) and in populations living in rural areas (p?0.001). A logistic regression model adjusted to marital status, socio-economic class, and area of living was performed. The following conditions were significantly associated with pterygium: blepharitis (OR?=?1.71; 99.9% CI: 1.53-1.93), chalazia (OR?=?1.46; 99.9% CI: (1.19-1.78)), anxiety (OR?=?1.14, 99.9% CI: 0.98-1.33), and G6PD deficiency (OR?=?1.85; 99.9% CI: 1.11-3.07). schizophrenia (OR 0.31; 99.9% CI: 0.19-0.50) and smoking (OR 0.82; 99.9% CI: 0.76-0.89) were significantly less prevalent among pterygium patients.
Pterygium etiology is multifactorial. Some demographic, systemic, and periocular conditions are significantly more prevalent and some are less prevalent among pterygium patients. Better understanding of the pathophysiological association between those diseases and pterygium may help in its prevention and treatment.
