Citrullinemia is one of the five urea cycle defects and is caused by argininosuccinic acid synthetase deficiency ; conversion of citrulline to argininosuccinic acid is blocked. Severe hyperammonemia typically develops in the neonate within a few days and symptoms such as vomiting, lethargy, convulsion, coma follows rapidly. The diagnosis is supported by high citrulline level in serum, urine, CSF and decreased activity of argininosuccinic acid synthetase in liver biopsy. We experienced a 3-day-old male neonate with poor activity, lethargy, convulsion, and coma who was diagnosed as citrullinemia by markedly elevated plasma and urine citrulline level with hyperammonemia. We report this case with brief review of the related literature.

This clinical trial was undertaken on 32 infants and chhildren who had G-I symptoms caused by a few diseases, such as meningitis, parenteral infection and intestinal infection. Out of 32 patients, six had vomiting only, caused by meingitis and habitual vomiting, eighteen had vomiting and diarrhea both which caused by parenteral infection and rest of them (8) had diarrhea only, caused by intestinal infection. Polybutine syrup, which 5.0 ml contain 24 mg of trimebutine, was given to these patients as follows; 2.5 ml twice a day at 6 months of age, 5.0 ml twice a day at 6 months to one year and 10 ml three times a day at 1-5 years of age. In ten of 24 patients, who had vomiting only (6), vomiting and diarrhea (18), the symptoms were improved within 48 hours, and rest of them (10) was also shown the improvement of their symptoms within 5 days after medication. In comparison of polybutine treated group and not treated group, the effectiveness of polybutine treatment for the symptoms was statistically meaningful.

6.ChatGPT’s Potential in Dermatology Knowledge Retrieval:An Analysis Using Korean Dermatology Residency Examination Questions
Korean Journal of Dermatology 2024;62(3):143-151
Background:
The rapid evolution of artificial intelligence (AI), particularly large language models such as OpenAI’s ChatGPT, has significantly impacted various domains including healthcare. Dermatology can potentially benefit from the integration of ChatGPT.
Objective:
To analyze the performance of ChatGPT in dermatology, with particular focus on understanding the model’s capabilities and limitations when addressing dermatology questions.
Methods:
We employed 144 questions from Korean Dermatology Residency Evaluation Examinations. Questions were formatted consistently and fed to both GPT-4 and GPT-3.5 models. Performance was qualitatively assessed based on accuracy, completeness, and logical reasoning. Reasons for wrong answers were analyzed.
Results:
The overall correctness rate for GPT-4 was 70.8% and 59.0% for GPT-3.5. In terms of accuracy, 70.1% of the explanations were completely accurate. A total of 90.3% of responses provided by GPT-4 were complete in terms of content. Illogical reasoning was detected only in 4.9% of the answers. A total of 69.0% of wrong answers were attributed to information errors, followed by logical errors in 16.7%. There was no significant difference in the correctness rates among question types, but the correctness rate decreased significantly with question difficulty. ChatGPT showed near-perfect consistency, demonstrating a 97.9% agreement and a Cohen’s kappa of 0.958.
Conclusion
This study demonstrated the potential of ChatGPT in dermatology knowledge retrieval, outperforming dermatology residents in terms of correctness rate, completeness, and accuracy. There were more information errors than logical errors, and the inaccuracy caused by these errors was identified as the main limiting factor of ChatGPT.

Hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease, is a rare autosomal dominant vascular disorder involving arteriovenous malformation. HHT is characterized by recurrent epistaxis, cutaneous telangiectasia, and visceral arteriovenous malformations. Hepatic arteriovenous malformation can lead to high output heart failure. We report a case of hereditary hemorrhagic telangiectasia patient who complained dyspnea and edema on both lower extremity.

One Hundred and eight patients received operation for acute subdural hematoma were evaluated in prognostic factors. They were admitted to the Neurosurgical Department in S.R.C.H during the 3 years from January, 1986 to December, 1988. The results were as follows ; 1) The patients were consist of 85 male patients and 23 female patients with the sex ratio 3.7 : 1. 2) Evaluated prognostic factors were age and sex, preoperative Glasgow coma scale(GCS), preoperative pathological physical findings, time interval from injury to operation, type of injury, midline shift, location of hematoma, thickness of hematoma, and operative procedure. 3) On the statistical analysis, factors of GCS and midline shift were considerable significant factors. 4) In the overall results of 108 patients, 47 patients(43.5%) had good recovery, 9 patients(8.3%) had moderate disabled state, 2 patients(1.9%) were severe disabled state, 4 patients(3.7%) were vegetative state, and 46 patients(42.6%) died.

The authors have analyzed the factors influencing the outcome of the 168 patients with acute epidural hematoma who had been managed in our hospital for 3 years from July 1986 to June 1989. 1) Sex incidence showed that male patients were 4.8 times more commonly affected than females, and the most commonly affected age group was the 3rd decade. 2) The most common cause of injury was motor vehicle accidents. The patients with unknown cause of injury which probably suggested significant delay in starting the clinical managements had a higher mortality rate. 3) The most common site of hematoma was the FTP convexity(63.6%). The patients with diffuse hematoma in the fronto-temporo-parietal region had a high mortality and deteriorated level of consciousness. 4) Skull fractures were not seen only in 9.5% of the patients with acute epidural hematoma. 5) The main factors associated with the higher mortality rate were rapid development of hematoma, pupillary dilatation, low score in Glasgow Coma Scale on arrival, and more midline shifting on brain CT. 6) The patients with concomitant intracranial lesions had a high mortality rate(25.8%), and the patients with acute epidural hematoma alone had a low rate(2%), and the overall mortality rate of the patients with acute epidural hematoma was 11.3%.

BACKGROUND/AIMS: Insertion of self-expanding metallic stents (SEMS) has become an established option for the palliation of malignant biliary obstruction (MBO). However, stent occlusion by tumor ingrowth is still an unsolved problem. To overcome this problem, membrane-covered SEMSs have been developed. The purpose of this study was to compare the effectiveness of membrane-covered SEMS versus plastic stent in the treatment of MBO. METHODS: Between Jan 2001 and Jul 2002, 57 patients with unresectable MBO who initially had plastic stents inserted were randomized to receive either plastic stent and membrane-covered SEMSs after initial plastic stent failure. RESULTS: Placement of either plastic stents or membrane-covered SEMs was successful in all patients. Mean patency duration of stents were significantly longer in membrane-covered SEMS group (189 days) than in plastic stent group (82 days) (p=0.01). The causes of stent failure were occlusion in 10 cases and migration in 1 case in membrane-covered SEMS group. Of these occluded 10 cases, tumor ingrowth was noted in 7, tumor overgrowth in 2, and biliary incrustation in 1. CONCLUSIONS: Membrane-covered SEMS has a longer patency than plastic stent. However, new membrane covering material is needed to prevent tumor ingrowth more effectively.
