Abstract
PURPOSE To describe clinical and ocular abnormalities in a case of Developmental Delay with Gastrointestinal, Cardiovascular, Genitourinary, and Skeletal Abnormalities (DEGCAGS syndrome). METHODS A clinical report. CASE DESCRIPTION An infant born to a consanguineous Middle Eastern family who was delivered by cesarean section because of in utero growth restriction, premature labor, and breech presentation. Post-partum medical problems included hypotension, generalized hypotonia, bradycardia, apnea requiring resuscitation and positive pressure ventilation, facial dysmorphia, skeletal malformations, and disorders of the gastrointestinal, immune, urinary, respiratory, cardiac, and visual systems. The family reported that a previous child had severe hypotonia at birth and was given the diagnosis of hypoxic ischemic encephalopathy; that child remains on a ventilator in a chronic care facility. Our patient was found to be homozygous for a novel pathogenic missense variant in theZNF699 zinc finger gene on chromosome 19p13 causing a syndrome known as Developmental Delay with Gastrointestinal, Cardiovascular, Genitourinary, and Skeletal Abnormalities (DEGCAGS syndrome). We review this variable syndrome, including abnormalities of the visual system not described previously. CONCLUSIONS We describe the 15th child to be presumably identified with the DEGCAGS syndrome and the first individual with homozygous missense variants in the ZNF699 gene who had complete clinical examination and detailed retinal imaging.

Abstract
BACKGROUND Resembling acute promyelocytic leukemia (APL) is a unique subtype of APL who sharing clinical, morphological, and immunophenotypic features with typical APL, but lacking evidence of PML-RARA fusion gene and usually insensitive to arsenic trioxide (ATO) and all-trans retinoic acid (ATRA). For years, RARA, RARB and RARG rearrangement were found in resembling APL continually. The confirmed partner genes of RARG rearrangement included CPSF6, NUP98, NPM1, PML, and HNRNPC. These patients were a group of resembling APL with rare molecular genetic abnormality and unfavorable prognosis. They usually were resistant to ATO and ATRA but partially sensitive to anthracycline-based chemotherapy. CASE PRESENTATION We reported a 25-year-old female patient with a novel fusion gene RARG-HNRNPM (RARG chr12:53606869: -; HNRNPM chr19: 8527413: + based on GRCh37/hg19 Assembly) through RNA-seq as resembling APL. The patient with RARG-HNRNPM was benefited from a combined chemotherapy homoharringtonine, cytarabine, and aclacinomycin (HAA) regimen with no relapse. DISCUSSION AND CONCLUSIONS RARG rearrangement resembling APL are various. The treatment should be switched from ATRA/ATO to AML combined chemotherapy regimen early.

Abstract
OBJECTIVE To investigate the clinical and laboratory features of acute myeloid leukemia (AML) with t(11;12)(p15;q13) translocation. METHODS Two cases of AML with t(11;12)(p15;q13) translocation were reported and the related literatures were reviewed. RESULTS The diagnosis of AML-M3 was supported by morphological, cytochemical staining and electron microscope tests. A rare t(11;12)(p15;q13) translocation, but not classical t(15;17)(q22;q12) translocation and PML- RARα fusion gene, was detected in both cases. Both of the patients were refractory to differentiation induction therapy such as retinoic acid and arsenic trioxide. CONCLUSION AML is a group of heterogeneous disease derived from hematopoietic stem cell. Cytogenetic characteristic is important for diagnosis, prognosis stratification and therapy selection. Because of the heterogeneity of clinical and molecular features, it is unsuitable to classify AML with t(11;12)(p15;q13) as AML with recurrent cytogenetic aberration. This group of disease may benefit from allogeneic hematopoietic stem cell transplantation.

Abstract
PURPOSE To compare the rectal and prostatic radiation doses for a prospective series of 503 patients, 44 of whom developed persistent rectal bleeding, and 2 of whom developed rectal-prostatic fistulas. METHODS AND MATERIALS The 503 patients were randomized and treated by implantation with 125I vs. 103Pd alone (n = 290) or to 103Pd with 20 Gy vs. 44 Gy supplemental external beam radiotherapy (n = 213) and treated at the Puget Sound Veterans Affairs Medical Center (n = 227), Schiffler Cancer Center (n = 242) or University of Washington (n = 34). Patients were treated between September 1998 and October 2001 and had a minimum of 24 months of follow-up. The patient groups were treated concurrently. Treatment-related morbidity was monitored by mailed questionnaires, using standard American Urological Association and Radiation Therapy Oncology Group criteria, at 1, 3, 6, 12, 18, and 24 months. Patients who reported Grade 1 or greater Radiation Therapy Oncology Group rectal morbidity were interviewed by telephone to clarify details regarding their rectal bleeding. Those who reported persistent bleeding, lasting for >1 month were included as having Grade 2 toxicity. Three of the patients with rectal bleeding required a colostomy, two of whom developed a fistula. No patient was lost to follow-up. The rectal doses were defined as the rectal volume in cubic centimeters that received >50%, 100%, 200%, or 300% of the prescription dose. The rectum was considered as a solid structure defined by the outer wall, without attempting to differentiate the inner wall or contents. RESULTS Persistent rectal bleeding occurred in 44 of the 502 patients, 32 of whom (73%) underwent confirmatory endoscopy. In univariate analysis, multiple parameters were associated with late rectal bleeding, including all rectal brachytherapy indexes. In multivariate analysis, however, only the rectal volume that received >100% of the dose was significantly predictive of bleeding. Rectal fistulas occurred in 2 patients (0.4%), both of whom had received moderate rectal radiation doses and extensive intervention for rectal bleeding. CONCLUSION Partly on the basis of data from others and data presented here, we believe that the incidence of rectal fistulas can be much lower than in our series. High rectal radiation doses should be avoided a priori, to minimize the likelihood of rectal bleeding, and hence the likelihood that invasive procedures will be performed.
