The Edinburgh Postnatal Depression Scale: validation for an Italian sample.

A sample of 113 women has been recruited for the Italian validation of Edinburgh Post Natal Depression Scale (EPDS). These women, between the eighth and the twelfth week after delivery, were admnistered the EPDS and diagnosed according the DSM-III-R criteria using the MINI Interview. At the 8/9 cut-off score the sensitivity is 94.4%, specificity 87.4% and PPV 58.6%. The internal consistency of the EPDS Italian version was tested using Chronbach's alpha coefficient (0.7894) and Guttman split-half coefficient (0.8191). Finally a receiver operating characteristic (ROC) analysis was carried out to evaluate the global functioning of the scale: the area under ROC curve AUC is 0.7470 and the logistic estimate for the threshold score of 11/12 fitted the model sensitivity at 75% and model specificity at 67%. Our data confirm the validity of EPDS in identifying postnatal depression also in its Italian version and the scale could be used as an useful instrument in the clinical practice.

Effects of chronic lithium treatment on the peripheral nervous system.

BACKGROUND: Although lithium carbonate is widely used in the treatment of mood disorders, symptoms suggesting toxic effects on the peripheral nervous system may emerge even in subjects whose serum lithium levels remain within the recommended therapeutic range. METHOD: Electroneuronographic (ENG) parameters (motor nerve conduction velocity of peroneal and median nerves, sensory nerve conduction velocity of sural and median nerves, amplitude of motor potential of peroneal and median nerves, and amplitude of sensory action potential of the median nerve at the wrist and the sural nerve) were investigated in 2 groups (N = 34) of patients suffering from bipolar affective disorder (DSM-III-R, DSM-IV) undergoing maintenance treatment with lithium carbonate for at least 1 year (mean = 2.06 years) in monotherapy. For 12 patients, ENG results were compared with pretreatment values, whereas in the other 22 cases, only data relevant to posttreatment were available. Fifty-four healthy subjects and 20 patients with recurrent major affective disorder (unipolar and bipolar) never treated with lithium made up the comparison groups. RESULTS: Compared with the 2 comparison groups, patients on chronic lithium treatment showed significant reduction of motor nerve conduction velocity of peroneal and median nerves, sensory nerve conduction velocity of sural and median nerves, amplitude of motor potential of peroneal and median nerves, and amplitude of sensory action potential of the median nerve at the wrist and the sural nerve. The comparison with the assessment made prior to lithium treatment also showed significant changes; after a period of treatment with lithium varying from 2 to 8 years (mean = 5.2 years), significant reductions were found on motor and sensory nerve conduction velocity and on amplitude motor potentials and sensory action potentials. CONCLUSION: Chronic maintenance treatment with lithium affects the peripheral nerves, even if the impairment rarely is such as to warrant discontinuation of treatment. Monitoring of ENG results could be useful for the early detection of neurotoxicity of lithium.

An Italian model of dementia special care unit: results of a pilot study.

A small feasibility study was performed in Italy to evaluate whether the special care unit (SCU) model could minimize behavioral disturbances in demented patients. In a nursing home an area was selected to provide an appropriate environment for individuals with dementia. The physical environment was adapted, and the staff was trained to meet the needs of demented patients. Sixteen residents were transferred from traditional wards to the SCU. Functional status, cognitive performance, behavioral symptoms, and use of psychotropic drugs or physical restraints were assessed before and 6 months after admission to the SCU. Our findings show that transferring demented persons from traditional nursing home wards to an SCU significantly lessens behavioral problems but does not improve functional abilities or cognitive status after a short period of follow-up. Changes in caring strategies (in particular the use of physical restraints) seem to be important in reducing behavioral problems. The regional government of Lombardia (8.5 million inhabitants) decided to open small (20-bed) SCUs in 60 nursing homes (corresponding to 3.5% of the total nursing home beds in our region) and to reserve these units for demented patients with a high level of behavioral disturbances.

The psychosis of fatherhood: a clinical study.

The psychosis of fatherhood is classified as an acute delusional disorder. It has been psychodynamically correlated with preoedipal conflicts. Common elements were identified in 6 men who were about to become fathers for the first time. Their personal histories and their clinical pictures were very similar. It is our hypothesis that up to the moment of facing the impact of becoming fathers themselves, these subjects had managed to avoid the oedipal conflict. As a consequence of this avoidance, they failed to identify with the father figure and to incorporate the paternal function into their symbolic universe. Once they accepted the concrete reality of fatherhood, these men underwent an acute psychotic crisis having inadequately interiorized paternal role models for themselves. We believe that this sort of psychopathological behavior becomes clinically manifest only when triggered by impending fatherhood.

[Progressive pneumoperitoneum in the surgical treatment of conspicuous ventral hernias. Importance of the procedure to restore a good respiratory function].

A recent clinical report regarding a patient with a voluminous laparocele treated using progressive pneumoperitoneum justifies this short paper on the use of this method as a preparatory act to reparative surgery. The paper emphasises the undoubted advantages deriving from the use of this technique, especially in the case of those subjects with a particularly poor respiratory function secondary to hernia.

[Pneumoperitoneum in preparation for surgery of large ventral hernia].

Reparative surgery of ventral hernia may be relatively simple or, on the other hand, the surgeon may be confronted with a number of tactical and technical problems. Many of these are caused by the "loss of the right of domicile". In order to avoid this particular condition it is useful to resort to preoperative pneumoperitoneum. This method entails the gradual and progressive introduction of air into the peritoneal cavity. In this way abdominal capacity is increased and it is therefore possible to re-insert all the viscera into their natural cavities avoiding all the harmful consequences for respiratory and cardio-circulatory organs following forced replacement. Preoperative pneumo-peritoneum is a relatively well consolidated surgical technique in large scale eventration. The methods is simple to perform and has a low incidence of complications.

[Therapeutic approach in ventral hernia].

Laparoceles are diseases of the abdominal wall and their repair does not usually involve technical problems which are difficult to resolve. The use of classic surgical methods, such as direct suture and plastic surgery, enables the parietal defect to be easily repaired in most case. However, cases do occur in which the surgeon is faced with considerable technical and tactical difficulties largely due to anatomopathological causes: the "loss of the right of domicile" of herniated viscera and the loss of musculo-aponeurotic substance. In the former case it is necessary to prepare the peritoneal cavity using pneumoperitoneum. In the event of the extensive destruction of the muscular component, or when the parietal breech is located next to bone or cartilagenous structures, it is essential to use a prosthesis. The paper goes on to describe the indications for the use of various techniques and their respective methods of use under different anatomo-clinical conditions.

[Progressive pneumoperitoneum in the preparation for surgical intervention for voluminous ventral hernias].

The paper report three patients suffering from voluminous ventral hernias who were treated using progressive pneumoperitoneum as a preparative method prior to reparative surgery. On the basis of the results obtained, the authors sustain the rationality, safety and efficacy of the procedure, in particular given its ability to reestablish good respiratory and circulatory function in those cases where the latter were severely affected by hernia. Since this method needs a longer application time and therefore involves a greater economic burden, pneumoperitoneum should probably be reserved for selected cases, and alternative techniques should be used in patients where hernia is more easily resolved.

Puerperal psychoses: a clinical case study with follow-up.

Thirty cases of post-partum psychotic disorders occurred between 1973 and 1987 and hospitalized at the Psychiatric Ward of Florence University were studied and followed up. A structured diagnostic interview was used, which explored DSM Ill-R diagnosis both for mood disorders and for psychotic features. The psychotic symptoms had started within 8 weeks of parturition in all cases. Only 36.7% of the patients showed no subsequent pathology after the puerperal symptoms. The diagnoses, both at the index episode and at the follow-up, revealed a great predominance of mood disorders and the absence of schizophrenia. The follow-up survey showed a greater proportion of bipolar disorders than it appeared at the puerperal onset of the disease. A high frequency of puerperal psychotic relapses has also occurred after subsequent deliveries during the follow-up period.

[Malignant tumors of the small intestine. Comments concerning 21 observed cases].

Patients affected by malignant tumors of the small intestine observed by the Department of Clinical and Pathological Surgery at the University of Florence were studied from 1964 to 1989. The most important aspects of the disease were studied, on the one hand emphasising its low incidence and on the other the poor prognosis which accompanies it. Greater attention should be focused on these lesions in order to enable an early diagnosis to be made since this currently represents the sole possibility for carrying out an efficacious therapy.

[Endometriosis].

On the basis of two recently treated cases of endometriosis, the main aspects of this unusual pathology are examined; in particular its aetiopathogenesis, clinical picture and treatment still provide reasons of uncertainty. On the basis of an albeit limited experience, stress is laid on the importance of radical surgery, the only way to resolve the situation. Medical or conservative surgical measures are left to the early stages of the disease.

[Disability and rehabilitation outcome in hemiplegia with global aphasia and neglect].

PURPOSE: Global aphasia and neglect are considered to be the neuropsychological disorders mostly affecting the hemiplegia outcome. The aim of this study is to examine which of the two disorders is making worse the recovery from hemiplegia. METHODS: The study was conduced on 45 patients suffering from hemiplegia: 15 subject with global aphasia, 15 with neglect and 15 without neuropsychological disorders (control group). All patients were subject to rehabilitation treatment. Before and after rehabilitation, the assessment of patients was made using neuropsychological tests, Fugl-Meyer scale and Functional Independence Measure (FIM). At admission, all patients were not self-sufficient. RESULTS: At the end of the rehabilitation period the recovery of motor function was poor in both groups. The damage on limbs motion was severe in 93.4% and marked in 6.6% of both patients with global aphasia and neglect. At discharge, the FIM motor score of patients with global aphasia (44.6 +/- 13) was higher than in those with neglect (37.2 +/- 10) and was not statistically different from control group (51.2 +/- 18) (p = 0.493). The FIM motor score of patients with neglect was significantly lower than control group (p = 0.036). In patients with global aphasia effectiveness was 35.5% and efficiency 0.40 while in patients with neglect effectiveness was 18% and efficiency 0.22. The final disability was lower in patients subject to global aphasia than neglect. CONCLUSIONS: The study showed that neglect limits the recovery from stroke more than global aphasia.e.
