Neurotoxicity of halogenated hydroxyquinolines: clinical analysis of cases reported outside Japan.

An analysis is presented of 220 cases of possible neurotoxic reactions to halogenated hydroxyquinolines reported from outside Japan. In 80 cases insufficient information was available for adequate comment and in 29 a relationship to the administration of clioquinol could be excluded. Of the remainder, a relationship to clioquinol was considered probable in 42 and possible in 69 cases. In six of the probable cases the neurological disturbance consisted of an acute reversible encephalopathy usually related to the ingestion of a high dose of clioquinol over a short period. The most common manifestation, observed in 15 further cases, was isolated optic atrophy. This was most frequently found in children, many of whom had received clioquinol as treatment for acrodermatitis enteropathica. In the remaining cases, a combination of myelopathy, visual disturbance, and peripheral neuropathy was the most common manifestation. Isolated myelopathy or peripheral neuropathy, or these manifestations occurring together, were infrequent. The onset of all manifestations (except toxic encephalopathy) was usually subacute, with subsequent partial recovery. Older subjects tended to display more side effects. The full syndrome of subacute myelo-optic neuropathy was more frequent in women, but they tended to have taken greater quantities of the drug.

[Clinico-morphological analysis of clinically unrecognized subdural hematomas].

The authors report clinical and morphological analysis of 31 autopsied cases of subdural haematomas unrecognized during life. The most frequent erroneous clinical diagnosis was cerebrovascular brain disease, psychiatric syndrome or brain tumour. The greatest diagnostic difficulties were encountered in cases of subdural haematoma developing in elderly subjects (in this material 24 patients were aged above 60 years). Brain atrophy delayed in them the appearance of intracranial raised pressure syndrome, coexistence of vascular changes masked the signs of subdural haematoma and frequent memory disturbances made history taking difficult. Brain atrophy in elderly subjects may be also a factor contributing to development of subdural haematoma. Widening of subdural space causes greater tension of bridging veins and their easier rupture when the brain is displaced during trauma. Absence of inflammatory changes in the neuropathological findings in cases of subdural haemorrhage suggests that the term "chronic subdural haematoma" is better than the older term "pachymeningitis haemorrhagic interna".

Clinical analysis of Fuchs' heterochromic cyclitis.

Fuchs' heterochromic cyclitis (FHC) is an important diagnosis to make. Not only for the patient, because incorrect diagnosis may lead to unnecessary therapy and the failure to detect secondary glaucoma, but also for the comparison of studies on the etiology of FHC, which is still unknown. No clinical criteria for establishing the diagnosis of FHC have been internationally accepted yet. By means of clinical analyses of FHC patients in different parts of the world, predominant clinical features may be distinguished and combined to form (internationally accepted) diagnostic criteria. We report a clinical analysis of 51 FHC patients in the Netherlands. Acute symptoms (severe redness, pain or photophobia) were never (100%) encountered. Characteristic keratic precipitates (88%) and/or minimal aqueous cells and flare (60%) and/or vitreous opacities (84%) were major signs, indicating a chronic inflammatory activity, in which no synechiae (100%) were present. Heterochromia (82%) was not a constant sign, but iris stromal atrophy, which causes the heterochromia, was always present (100%). Cataract was present in 82% as a result of the chronic iridocyclitis. Secondary glaucoma was present in 22%. Based on the predominant clinical findings obtained from this analysis of FHC patients, and on data in the literature, we propose clinical diagnostic criteria for FHC. Future studies, also including other uveitis groups, are necessary to confirm these diagnostic criteria.

[A case of inverted Y ureteral duplication with an ectopic ureterocele].

A 29 year-old male with the complaints of two steps urination and sense of residual urine was admitted. At cystoscopy, a ureterocele was found between the normal left ureteric orifice and the bladder neck. Excretory urography demonstrated a radiolucent area in the bladder and a left lower hydroureter. Retrograde pyelography revealed that the left ureter was divided into two branches. Operative exploration demonstrated that the left ureter was an inverted Y ureteral duplication with an ectopic ureterocele; one opened into the ureterocele and the other into the trigone. We resected the ureterocele wall. Four months later, a voiding cystogram did not show vesicoureteric reflux. Now, he has no symptoms and the results of examination are normal. An inverted Y ureteral duplication is the rarest of all anomalies of the ureter. A review of the literature revealed 36 cases reported previously. Clinical analysis was obtained by reviewing 26 of these cases and adding our own (male 10: female 17, average age: 23 years). Complication included 6 cases of ectopic ureteral opening, 6 with blind-ending branch and 5 with ureterocele. The symptoms of this disease depended on the complicating anomalies. The present case was the 5th one of an inverted Y ureteral duplication with a ureterocele in the world literature.

Breast Cancer Recurrence Status Assessment in 5 Years Using Multimodal Integrated Learning: A Feasibility Study.

Despite advances in breast cancer detection and treatment, recurrence after curative therapy continues to impact long-term survival and quality of life. Therefore, early identification of high-risk patients is crucial to guide personalized treatment and follow-up strategies. Although genomic assays provide valuable prognostic insights, their high cost and limited accessibility hinder widespread adoption in clinical practice. Recent machine learning or deep learning approaches leveraging clinical, imaging, or multimodal data have shown promise but do not reflect real-world clinical scenarios. This study proposes a deep learning-based multimodal framework for predicting 5-year breast cancer recurrence using routinely collected clinical data. The framework consists of three main components. First, we adopted automated tumor segmentation with MedSAM to extract the tumor region from ultrasound images. The radiomics features are extracted from those tumor regions. Second, report features are extracted using a Med-Contrastive Pre-trained Transformers (MedCPT)-based approach incorporating predefined, clinically informed queries. Third, a multimodal integration model jointly processes image, radiomics, clinical features, and report features through modality-specific branches. The image branch employs the Ultrasound Foundation Model (USFM) as the backbone, while structured tabular data is processed using the FT-Transformer architecture. The features of all branches are fused using a mixture-of-experts (MoE)-based classifier, and the entire model is trained using a progressive fusion training strategy. Experimental results confirm the feasibility of using ultrasound images with tumor mask integration for recurrence prediction and demonstrate the additive value of integrating multiple data modalities through the proposed multimodal integration model. The final model for recurrence prediction achieved an AUC of 0.7540, accuracy of 74.61%, sensitivity of 70.41%, and specificity of 76.44%. This feasibility study's findings underscore the potential of the proposed multimodal deep learning framework to provide accessible, accurate, and generalizable recurrence risk prediction using routinely available clinical data, potentially supporting more informed treatment decisions and personalized post-treatment monitoring in real-world clinical practice.

Home parenteral nutrition--a 3-year analysis of clinical and laboratory monitoring.

We report a 3-year analysis (1986 to 1989) of the management of 63 home parenteral nutrition patients, 40 with short-bowel syndrome and 23 with chronic intestinal obstruction with or without intestinal resection. Intravenous fluid requirements varied from 0.9 to 6 L/day, and the content of glucose varied between 46 and 531 g/day, protein varied from .0 to 85 g/day, fat from .0 to 100 g/day, sodium from 37 to 695 mEq/day, potassium from 30 to 220 mEq/day, chloride from 60 to 760 mEq/day, and acetate from 0 to 200 mEq/day. Body weight was normalized and well maintained in the majority of patients, but using the strict definition of deficiency as the presence of one abnormal value during 3 years, more than half had abnormal plasma chloride, glucose, alkaline phosphatase, serum glutamic oxaloacetic transaminase, total protein, albumin, selenium, and iron concentrations, and more than a third had low calcium, magnesium, vitamin D, and vitamin C levels. Normochromic anemia was seen in 73% and high blood creatinine associated with low urine volumes in 42%. Most (78%) returned to relatively normal lifestyles, but employability was occasionally impaired by loss of third-party insurance coverage resulting from a therapy that may cost $100,000 per year. Overall mortality was low (5% per year), but 73% needed readmission to hospital, mainly for suspected catheter sepsis. The results indicate that home parenteral nutrition has allowed many patients to survive gut failure and return to work but problems with chronic fluid, electrolyte and micronutrient deficiencies, catheter sepsis, and insurance coverage often restrict optimal rehabilitation.

Assessment of study design in clinical trials for bladder cancer.

Physicians and surgeons who treat bladder cancer must be able to judge the validity and relevance of clinical trials if they are to make appropriate recommendations to their patients. To do so, they must be familiar with the design of clinical trials and with the many problems that may confound their results and limit their validity. The present article has reviewed aspects of the design, analysis, and reporting of clinical trials with particular reference to bladder cancer. Nonrandomized studies are important in establishing the feasibility of new treatments and in providing preliminary information about effectiveness. However, selection of patients, together with many other types of bias, prevents a useful comparison of the results obtained in such trials with those obtained using alternative treatment strategies. Establishment of the value of a new type of treatment will usually require the conduct of a large randomized trial in which patients receive experimental or standard therapy by random assignment. While such trials may influence practice in an appropriate way, they must likewise be reviewed critically to ensure the validity of the results and generalizability to patients seen in a nontrial setting.

Preoperative radiation for carcinoma of the thoracic esophagus involving adjacent organs--a comparative and multivariate analysis of prognosis.

Controversy remains over the comparative efficacy and subsequent prognosis for preoperative radiation for carcinoma of the esophagus involving the trachea, bronchus, and/or aorta. Results of a multi-variate analysis are reported using clinical data from 57 cases from 1981 to 1987. Based on both the survival-rate curves using the Kaplan-Meier method and the adjusted survival-rate curves using Cox's proportional hazards linear model, there was no significant difference in prognosis between patients who received preoperative radiation and those who did not. This analysis indicates that preoperative radiation at doses of 30Gy produces no clinical advantage and therefore is not the best treatment for carcinoma of the esophagus involving these adjacent organs.
