PURPOSE: Newborn infants with diarrhea, metabolic acidosis and dehydration may develop methemoglobinemia without exposure to oxidizing agents. This study was undertaken to investigate clinical features in the development of methemoglobinemia in newborn infants with diarrhea. METHOD: This study involved 16 newborn infants with diarrhea who were admitted to NICU at Dong San Medical Center between January 1995 and June 1996. We investigated the age of onset of methemoglobinemia, sex ratio, level of methemoglobin in the blood, feeding methods, clinical manifestations, arterial blood gas findings, the results of culture findings and the response to therapy. RESULT: 1) The age of onset was beyond the second week of life in most cases, no sex predilection was noted and formula feeding was used in all cases. 2) Methemoglobin level in the blood was 10.1-20.0% in 7 cases, 20.1-30.0% in 6 cases, 30.1-40.0% in 2 cases and above 40.1% in one case. 3) Clinical rnanifestations on admission: moderate to severe dehydration developed in all patients with diarrhea along with respiratory distress in 13 cases, cyanosis in 6 cases, fever was noted in 5 cases, vomiting in 5 cases, while 2 cases presented with abdominal distention. Combined diseases included metabolic acidosis in most cases (93.8%), hypokalemia in 6, failure to thrive in 3, chronic diarrhea in 2, hyponatremia in 2, necrotizing enterocolitis in 1 and hepatitis was found in one case. 4) In all cases, there were no pathogenic organisms found in either blood or urine cultures along with similar negative findings in stool cultures, and Rotazyme test results using ELISA method were negative. 5) Rehydration and correction of acidosis with sodium bicarbonate was accomplished in all patients and 11 cases with greater than 15% methemoglobin were treated with methylene blue, 2mg/kg as a 1% solution in normal saline. Response to methylene blue was indicated in 1 to 2 hours in all cases although there was a reoccurrence of methemoglobinemia after an initial response in 2 cases, they both responded favorably with retreatment with methylene blue. CONCLUSION: In all newborn infant with diarrhea, dehydration and metabolic acidosis, screening tests for early diagnosis of methemoglobinemia should be considered with prompt fluid replacement therapy.

BACKGROUND: Squamous cell caircinoma(SCC) often shows acantholysis as a result of degenerative changes of neoplastic cells. Regurding the acantholytic changes of SCC most textbooks and literature describe the acantholysis-associated tubular or alveolar structures, which are diagnostic features of adenoid SCC. But the acantholytic changes of SCC are not always assaciated with tubular or alveolar structres. The general and detailed histologic features of acantholysis of SCC have not been reported. OBJECTIVE: We analyzed the histologic features of acantholysis of SCC . MEHTODS: Twenty six biopsy specimens from 26 patients with SCC were studied for the distributions and sites of acantholysis such as lefts and tubular or alveolar structurs on routine histologic staining. RESULTS: All 26 biopsy specimens showed acantholysis in their tumors ocal acantholysis was found in 12 cases, and diffuse, widesprcad acantholysis was found in 14 cascs. The foci of acantholysis were in the surface epidermis in 9 cases, in the follicular wall in 5 cases, and in both the surface epidermis and the follicuar wall in 12 cases. The types of acantholytic cells were either dyskeratotic cells or non-dyskeratotic squamous cells. Tuthular or alveolar structures were found in 5 cases. Clefts were found in 12 cases, one in the subcomealarea, the other 11 were within tumor mases, and one of them showed Darier-like feature with papillary projections of neoplastic cells into thc lumens. CONCLUSION: The acantholytic hanges of the SCC are more comrr on y found than expected. The acantholytic changes involve not only dyskeratotic cells but also non-dysL eratotic cells and often show glandular structures and clefts.

Wiskott-Aldrich Syndrome is an X-linked disorder characterized by recurrent infection, thrombocypenia and eczema. Various defects in cell-mediated immunity and deficient antibody reponse to carbohydrate antigens have been described. We experienced a case of Wiskott-Aldrich Syndrome of 28 months old male patient. He has been suffered from multiple petechiae with bleeding, recurrent pyogenic infections and generalized eczema since 3 months of age. Immunological abnormalities are as follows: 1) Serum IgM was gradually decreased, while IgA and IgE were increased. 2) Antibody response against polysaccharide antigen (PRP) was not observed after 3 times of PRPT immunization. 3) CD4/CD8 ratio was reversed (0.6). 4) Proliferative response of mononuclear cells was significantly reduced, and CMI skin test also showed negative results. A brief review of literature was made.

From Sept. 1987 to Mar. 1993, 14 cases of pelvic bone tumors took surgical treatment. Male to female ratio was 7:7, with an average age of 31.9 years. Pathological diagnosis were chondrosarcoma 7(1 ; secondary), metastatic thyroid cancer 2, and each one case of giant cell tumor, desmoplastic fibroma, metastatic synovial sarcoma, malignant fibrous histiocytoma(MFH), and enchondroma. According to the Enneking's classification for the type of surgical resection, we performed 4 cases of type II+III resection, 4 type IA, 2 type I+II, 2 type III, and each one of II and IIA+III. Types of reconstruction were hip fusion(3 cases), heat treated autogenous bone graft combined with total hip replacement arthroplasty(4), bone graft(2), cement spacer(1) or saddle prothesis(1). Simple resection was done for 3 cases. Wide surgical margin was achieved in 12 cases, marginal margin in 1 and intralesional magin in 1. Complications occurred in 3 cases(21.4%) : 1 graft failure ; 1 lymphedema ; and 1 delayed union. The average follow-up period was 27.4(8-60) months. During follow up, lung metastasis developed in MFH case but no local recurrence was noted in all. By the criteria of American Musculoskeletal Tumor Society(MSTS), the average score for functional activities was 21(70% of normal). The function of the extremity with reconstructed or undestroyed pelvic ring was better than that with disrupted pelvic ring(functional scores ; 24.6 vs 12.3 respectively). Due to the Korean life style using hypocaust, fused hip was not good for indoor activity. For the malignant pelvic bone tumor not involving femoral neurovascular bundle, limb-salvage using internal pelvectomy and reconstruction of pelvic ring can be indicated as a surgical procedure, instead of the hindquarter amputation.
