Intraluminal duodenal diverticulum (IDD) is a rare congenital abnormality, consisting of a sac-like mucosal lesion in the duodenum. Cases of IDD can present with gastrointestinal bleeding, duodenal obstruction, or pancreatitis. Here, we report a rare case of a 25-year-old female presenting with IDD complicated by duodeno-duodenal intussusception and recurrent pancreatitis. The diagnosis was based on findings from radiologic examinations (CT and MRI), upper gastrointestinal series (barium swallow), and gastroduodenofiberscopy. Laparoscopic excision of the presumed duodenal duplication was performed. The subsequent histopathologic evaluation of the excised sac revealed normal mucosa on both sides, but the absence of a proper muscle layer confirmed the diagnosis of IDD. Radiologic detection of a saccular structure in the second portion of the duodenum can indicate IDD with duodeno-duodenal intussusception as the lead point

We present a case of complete vaginal stenosis in a woman diagnosed with Sheehan’s syndrome. The patient delivered at full-term 5 months prior, and experienced massive postpartum bleeding at that time. During evaluation of persistent amenorrhea, we found that her vaginal orifice was completely adhesive and obstructed. Prior to corrective surgery, we managed the patient with an oral contraceptive to induce uterine bleeding into the vaginal outflow tract. After three cycles of an oral contraceptive, we could confirm that there was no stenotic lesion in the vaginal cavity as a hematocolpos was created. Adhesiolysis with scar revision for the vaginal stenosis was successfully performed; it was found that the lesion was limited to only the distal part of the vaginal outlet. Complete vaginal stenosis in reproductive age women with hypopituitarism has not been reported. The artificial induction of hematometrocolpos before surgery was useful in determining the extent of the stenotic lesion, and assured safety.

For many years it had been universally taught that administration of the commonly used analgesic agents retards the progress of labor. It was therefore advised that these agents should not be administered until the labor was active and progress was rapid. In recent years, more scientific analysis of the progress of labor and accurate recording of uterine contractility revealed that this classical teaching was inaccurate. Despite the increasing use of regional analgesia during labor, systemic medications are still widely used to relieve pain and anxiety. There is no ideal, generally applicable analgesic agent for use during childbirth. All systemic medications used for pain relief in labor cross the placenta and may have a depressant effect on the fetus and injudicious administration of an overdose can cause some depression of uterine activity. It is suggested that elimination of pain or anxiety will decrease adrenal medullary release of epinephrine. Since epinephrine is a known inhibitor of uterine activity, a decrease in its serum level should lead to increased uterine activity. Thus it was decided to make an objective estimation of the effects of morphine, meperidine, diazepam and ketamine upon uterine contractility of pregnant rat uteri, in vitro. The results are as follows: 1) Morphine caused a significant concentration dependent decrease in the contractility of pregnant rat uteri. 2) Meperidene did not cause any significant change in the contractility of pregnant rat uteri. 3) Diazempam caused a concentration dependent decrease in the contractility and the contraction disappeared at a concentration of 80 ug/100ml. 4) Ketamine caused a significant concentration dependent decrease in the contractility of pregnant rat uteri. 5) Addition of CaCl2 to the K-H solution did not cause any significant change in the result.

Endometriosis is defined by the presence of extrauterine endometrial tissue and presents with symptoms of dysmenorrhea, chronic pelvic pain, and impaired fertility. This condition often follows a chronic progressive course with favorable recurrence, even after surgical or medical treatment. The etiology or exact pathophysiology of endometriosis remains to be clarified, although it is thought to be a complex and multifactorial disease. Prior epidemiological or population-based studies have reported several risk factors related to endometriosis, such as environmental, menstrual, habitual, and lifestyle factors. Moreover, anthropometry has been found to be significantly associated with the diagnosis of endometriosis, as a lower body mass index is associated with an elevated risk of endometriosis. Here, we review studies that have examined the association between body size and the risk of endometriosis and discuss the clinical and biological significance of the relationship between adiposity and endometriosis.

Stem cells are undifferentiated cells capable of self-renewal and differentiation into various cell lineages. Stem cells are responsible for the development of organs and regeneration of damaged tissues. The highly regenerative nature of the human endometrium during reproductive age suggests that stem cells play a critical role in endometrial physiology. Bone marrow-derived cells migrate to the uterus and participate in the healing and restoration of functionally or structurally damaged endometrium. This review summarizes recent research into the potential therapeutic effects of bone marrow-derived stem cells in conditions involving endometrial impairment.

Endometriosis is characterized by the implantation of endometrial cells outside the uterus. This hormone-dependent disease is highly prevalent among women of reproductive age. Clinical symptoms of endometriosis include dysmenorrhea, pelvic pain, and infertility, which can negatively impact the overall quality of life of those affected. The medical treatment of endometriosis serves as an important therapeutic option, aimed at alleviating pain associated with the condition and suppressing the growth of endometriotic lesions. As such, it is employed as an adjuvant therapy following surgery or an empirical treatment after the clinical diagnosis of endometriosis. Dienogest, a fourth-generation progestin, has received approval for the treatment of endometriosis in many countries. A growing body of evidence has demonstrated its efficacy in managing endometriosis-associated pain, preventing symptoms, and reducing lesion recurrence. In this review, we examine the clinical efficacy, safety, and tolerability of dienogest in treating endometriosis. We also provide updated findings, drawing from clinical studies that focus on the long-term use of this medication in patients with endometriosis.

The patterns of the conventional radiation treatment fields and their shielding blocks are analysed to determine the optimal dimension of the MultiLeaf Collimator (MLC) which is considered as an essential tool for conformal therapy. Total 1169 radiation fields from 303 patients (203 from Asan Medical center, 50 from Baek Hosp and 50 from Hanyang Univ. Hosp.) were analysed for this study. Weighted case selection treatment site (from The Korean Society of Therapeutic Radiology 1003). Ninety one percent of total fields have shielding blocks. Y axis is defined as leaf movement direction and it is assumed that MLC is installed on the cranial-caudal direction. The length of X axis were distributed from 4cm to 40cm (less than 21cm for 95% of cases), and Y axis from 5cm to 38cm (less than 22cm for 95% of cases). The shielding blocks extended to less than 6cm from center of the filed for 95% of the cases. Start length for ninety five percent of block is less than 10cm for X axis and 11cm for Y axis. Seventy six percent of shielding blocks could be placed by either X or Y axis direction, 7.9% only by Y axis, 5.1% only by X axis and it is reasonable to install MLC for Y direction. Ninety five percent of patients can be treated with coplanar rotation therapy without changing the collimator angle. Eleven percent of cases of cases were impossible to replace with MLC. Futher study of shielding should be larger than 21cm X 22cm. The MLC should be designed as a pair of 21 leaves with 1cm wide for an acceptable resolution and 17cm long to enable the leaf to overtravel at least 6cm from the treatment field center.

Although listeria monocytogenes is widely distributed in nature, it rarely causes clinical infection in previously healthy people. However, this microorganism may cause severe infectious disease in pregnant women and newborns due to impaired cell-mediated immunity. Various clinical symptoms have been described such as sepsis, central nervous system infections, endocarditis, gastroenteritis and localized infections. A clinical presentation of listeriosis in an early third trimester pregnant woman and in a preterm infant is emphasized in addition to taking a careful patient history, early empirical administration of antibiotics, aggressive ventilation therapy and also pharmacological support.

OBJECTIVES: In surgically treated non-small cell lung cancer, patients have a wide difference in prognosis even though they may be in the same stage. Therefore it is difficult to establish the prognosis for individual lung cancer patients. In this study, by using flow cytometric analysis of nuclear DNA content and S-phase fraction(SPF) of surgically treated non-small cell lung cancer patients, we proposed to establish other prognostic factors and their validity in comparison with the existing ones. METHODS: Paraffin-embedded tissue specimens from 81 surgically treated patients, diagnosed with non-small cell lung cancer ranging from stage I to stage IIIa, were analyzed by flow cytometrically determined nulear DNA content and S-phase fraction. Cellular DNA content stained with propidium iodide was analyzed by flow cytometry: histograms with a coefficient of variation exceeding 8% were not used. RESULTS: 1) DNA content analysis was carried out for 59 of 81 patients. Of the 59 patients who were investigated by flow cytometry, 45 (76.3%) of the tumors were DNA aneuploidy and 14 (23.7%) were DNA diploidy. The proportion of DNA aneuploidy tumors showed no significant difference between cell types or stage. 2) S-phase fraction was evaluated for 36 of 81 patients. Mean value of SPF was 19.2% (+/-12.62)%. The value of SPF had nothing to do with stage. 3) The proportion of the high SPF group (more than 10% of cell proliferation cycle) was 75% With advance staging, the proportion of the high SPF group increased. 4) Significant difference in the median survival time was observed between the low SPF group and the high SPF group (32 months in low SPF, 12 months in high SPF) (p<0.05). No significant difference in the median survival time was observed between the aneuploidy group and the diploidy group (19 months in aneuploidy, 34 months in diploidy). 5) Significant difference in the disease free median survival time was observed between the low SPF group and the high SPF group (5 months in low SPF, 19 months in high SPF) (p<0.05). No significant difference in the disease free median survival time was observed between the aneuploidy group and the diploidy group (12 months in aneuploidy, 34 months in diploidy). 6) Upon multivariate analysis, stage and high SPF (more than 10% of cell proliferation cycle) were significant prognostic factors in surgically treated non-small cell lung cancer patients. CONCLUSION: The TNM stage and high SPF were significant as prognostic factors in surgically treated non-small cell lung cancer patients. Therefore new treatment plan should be needed in the patients who have high SPF.

Bickerstaff's brainstem encephalitis is characterized by ophthalmoplegia, ataxia, and disturbance of consciousness. It is similar to Miller Fisher syndrome, a variant of Guillain-Barre syndrome, in that they share features such as ophthalmoplegia and ataxia. The difference is that patients with Bickerstaff's brainstem encephalitis have impaired consciousness, whereas patients with Miller Fisher syndrome have alert consciousness and areflexia. Here, we report the case of a 3-year-old child who was diagnosed with Bickerstaff's brainstem encephalitis presenting typical clinical features and interesting radiological findings. The patient showed ophthalmoplegia, ataxia, and subsequent stuporous mentality. Brain magnetic resonance imaging revealed high signal intensity in the pons and cerebellum around the 4th ventricle on a T2-weighted image. He was successfully treated with intravenous immunoglobulin. Differentiation of Bickerstaff's brainstem encephalitis and Miller Fisher syndrome is often difficult because they possess many overlapping features. Brain magnetic resonance imaging may be helpful in diagnosing Bickerstaff's brainstem encephalitis, especially when lesions are definitely found.
