Adenosquamous cell carcinoma (Ad-SCC) of the colon is rare. The pathogenesis of Ad-SCC is unclear, however, several hypotheses have been suggested. The clinical presentation and gross findings of Ad-SCC of the colon are similar to those of adenocarcinoma of the colon, but Ad-SCC has a more aggressive clinical course and a poorer prognosis. We report on two cases of Ad-SCC of the colon with obstruction; a collision-type Ad-SCC that has not only obstruction but also numerous hepatic metastases, and a composite-type Ad-SCC treated with left hemicolectomy followed by an adjuvant chemotherapy.

Until recently, the cervical pregnancy have been treated with surgery, usually hy- sterectomy, because of uncontrollable heavy vaginal bleeding. The development of sophisticated ultrasound which allows early diagnosis of cervical pregnancy and methotrexate chemotherapy opened up new therapeutic options in the management of this unusual but potentially life threatening complication of pregnancy which have been always a nightrnare for the gynecologist. We are reporting a case of cervical pregnancy diagnosed in 12 weeks of gestation. The patient was successfully treated with alternative administration of methotrexate (1 mg/kg, intramuscularly) and leucovorin (0.1 mg/kg, intramuscularly) without surgical intervention, in order to preserve both the uterus and fertility. Follow up was done with serum beta hCG and pelvic ultrasonography. Complete resolution of the cervical pregnancy was obtained at 50 days after starting methotrexate treatment. This case gave us the opportunity to review the recent literature on cervical pregnancy.

Lafora' disease is an autosomal recessive, fatal, generalized polyglucosan storage disorder that occurs in childhood or adolescence with stimulus sensitive epilepsy (resting and action myoclonias, grand mal, and absence), dementia, ataxia and rapid neurological deterioration. We present a 19-year-old, 32 kg woman with lafora's disease was scheduled for tonsillectomy under general anesthesia. Her preanesthetic examination revealed extreme muscle atrophy and dementia. Grand mal, myoclonic seizures, and upper airway obstruction were frequent. General anesthesia and tracheal intubation with sevoflurane and nitrous oxide provided safe anesthesia. The intraoperative course was uneventful and the emergence of anesthesia was smooth.

PURPOSE: Methylenetetrahydrofolate reductase (MTHFR) is a critical enzyme regulating folate level, which affects DNA synthesis and methylation. MTHFR is highly polymorphic, and its variant genotypes result in decreased MTHFR enzyme activity and lower plasma folate level. Generally, a low folate level is known to be associated with a gastrointestinal neoplasm. Three common single nucleotide polymorphisms (SNPs) resulting in amino-acid changes (C677T, A1298C and G1793A) have been reported in MTHFR. We studied the relationship of MTHFR C677T, A1298C and G1793A polymorphisms between from colon cancer group and control group of Korean people. METHODS: We performed a case- control study to examine the relationship between MTHFR C677, A1298C, and G1793A polymorphisms and the risk of colon cancer. Two hundred seven (207) individuals with colon cancer and 288 healthy persons were analyzed. Blood sampling of each group was performed, and (PCR-RFLP) was analyzed; as a result, MTHFR polymorphism genotypes were obtained. RESULTS: The genotype frequencies of MTHFR C677T polymorphisms were 27.1% (CC), 48.3% (CT), 24.6% (TT), and 72.9% (CT+TT) in the patient group and 39.2% (CC), 36.8% (CT), 24.0% (TT), and 60.8% (CT+TT) in the control group. The genotype frequencies of MTHFR A1298C polymorphisms were 58% (AA), 35.7% (AC), 6.3% (CC), and 42% (AC+CC) in the patient group and 55.6% (AA), 40.3% (AC), 4.2% (CC), and 44.4% (AC+CC) in control group. The genotype frequencies of MTHFR G1793A polymorphisms were 83% (GG), 15.9% (GA), 1% (AA), and 16.9% (GA+AA) in the patient group and 85.8% (GG), 11.8% (GA), 2.4% (AA), and 14.2% (GA+AA) in the control group. The 677CT genotype was associated with a significantly increased risk for colon cancer (adjusted OR=1.90, 95% confidence interval: 1.25~2.90 in CT) than the 677CC genotype. The 1298CC, 1298AC, 1793AA, and 1793GA genotypes were not associated with a significantly increased risk for colon cancer. CONCLUSIONS: The MTHFR C677T polymorphism may influence colon cancer, but the MTHFR A1298C and G1793A polymorphisms need to be studied further for careful interpretation and confirmation in larger studies.

Spontaneous cervical epidural hematoma (SCEH) is a rare condition that causes paraparesis or quadriparesis. As spontaneous resolution is seldom expected, it usually requires surgical treatment for relieve symptoms. Even if spontaneous resolution occurs, relief from symptoms usually requires several hours to days. In contrast, hemiparesis is the most common symptom of a transient ischemic attack (TIA), and usually resolves over minutes to hours. We report here two patients with SCEH who presented with hemiparesis with severe neck pain. Both patients were taking antiplatelet drugs. Their neurological symptoms recovered spontaneously over a very short time. They were initially misdiagnosed as TIA. These cases show that patients with transient hemiparesis may have SCEH if there is severe neck pain and no cranial nerve involvement.

To identify the central innervating the mammary nerve, viral retrograde transneuronal labelling methods were employed. Pseudorabies virus 6 microliter was injected into the mammary nerve of adult female Sprague-Dawley rats. After 4 days of survival, the animals were perfused with 4% paraformaldehyde-lysine periodate and their brains were processed for immunohistochemistry and double immunofluorescent staining of Pseudorabies virus or oxytocin using polyclonal antibodies. Several nuclei in brain were retrogradely labelled with Pesudorabies virus.Only a few magnocellular neurons of the paraventricular nucleus throughout whole brain showed double immunoreactivity to Pseudorabies virus and oxytocin. Approximately 11 percent of the oxytocinergic cells of the paraventricular nucleus,especially in three subnuclei[dorsomedial cap, lateral magnocelluar part and ventral part] showed double positive reaction to both Pseudorabies virus and oxytocin. These data demonstrate that some CNS cells projecting to the mammary nerve contained oxytocin and it may acts as a neurotransmitter in this pathway and a hormone targeting milk production and secretion.

Choriocarcinoma is an aggressively growing and widely metastasizing tumor that originates from trophoblastic cells. A primary gastric choriocarcinoma (PGC), however, is very rare. A 76-year-old female patient visited the emergency department of Wonkwang University Hospital with abdominal discomfort and melena. Esophagogastroduodenoscopy revealed a huge ulceroinfiltrative mass lesion with blood clots on the boundary between the greater curvature side and the posterior wall side of the stomach lower body. CT showed a 3-cm exophytic mass lesion with heterogeneous enhancement, an ulcer lesion at the posterior wall side of the stomach lower body, and multiple enlarged lymph nodes at the splenic artery and left gastric artery nodal stations. She underwent a radical subtotal gastrectomy with a D2 lymph node dissection. The final diagnosis was PGC coexisting with adenocarcinoma based on the pathology results. This paper reports a rare case of primary gastric choriocarcinoma coexisting with adenocarcinoma and discusses the characteristics of this neoplasm with reference to the literature.

Edema blisters is an acute bullous disease that occurs following acute lower leg edema in patients with heart, renal and liver disease. Most of the affected patients are elderly, immobile and have been hospitalized for a long time. These clinical situations are commonly observed, but this can be misdiagnosed as other bullous diseases, especially friction blisters and bullous pemphigoid. We herein report a case of acute edema blisters in a 74-year-old female who presented with a tense bullae based on an edematous lower leg.
