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

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.

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.

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.
6.What is the link between endometriosis and adiposity?
Obstetrics & Gynecology Science 2022;65(3):227-233
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.

BACKGROUND: We compared the association between economic status and the prevalence of diabetes mellitus (DM) using large nationwide datasets covering the previous 10 years in Korea. METHODS: We analyzed the association between economic status and DM using Korean National Health and Nutrition Examination Survey (KNHANES) data from 2001 to 2010 weighted to represent the Korean population between 30 and 59 years of age. The economic status of participants was classified into quartiles according to monthly family income with an equivalence scale. RESULTS: In men, the prevalence of diabetes in the lowest income quartile (Q1) was significantly higher than that in the other quartiles in 2008 (age and body mass index-adjusted odds ratio [OR], 1.846; 95% confidence interval [CI], 1.126 to 3.027; P=0.015), 2009 (OR, 1.706; 95% CI, 1.094 to 2.661; P=0.019), and 2010 (OR, 1.560; 95% CI, 1.024 to 2.377; P=0.039) but not in 2001 or 2005. The data indicated that classification in the lowest economic status was an independent risk factor for diabetes even after adjusting for abdominal obesity, dyslipidemia, hypertension and education level in men of KNHANES 2008 to 2010. Although economic status was significantly associated with abdominal obesity, hypertriglyceridemia, and hypertension in women (P<0.001), there was no significant association between economic status and DM in women. CONCLUSION: Korean men between 30 and 59 years of age with the lowest economic status had a significantly higher prevalence of DM in 2008 to 2010 even after adjusting for other risk factors.

A rapid increase in desflurane concentration induces hypertension and tachycardia and increases plasma catecholamine concentration. This sympathetic stimulation occurs when desflurane is inspired with high concentration shortly after anesthetic induction or when the inspired concentration of desflurane is rapidly increased during steady-state periods of anesthesia. We represent a case of increase of blood pressure and heart rate during desflurane inhalation in a patient with tracheostomy state.

Remote afterloading high dose rate brachytherapy(HDRB) is a new technology and needs new biological principle for time and dose schedule. Here, authors attempt to evaluate the technique and clinical outcome in 116 patients, 590 procedures performed at Asan Medical Center for 3 years. From Sep. 1985 to Aug 1992, 471 procedures of intracavitary radiation in 55 patients of cervical cancer and 26 of nasopharyngeal cancer, 79 intraluminal radiation in 12 of esophageal cancer, 11 of endobronchial cancer and 1 Klatskin tumor and 40 interstitial brachytherapy in 4 of breast cancer, 1 sarcoma and 1 urethral cancer were performed. Median follow-up was 7 months with range 1~31 months. All procedures except interstitial were performed under the local anesthesia and they were all well tolerated and completed the planned therapy except 6 patients. 53/58 patients with cervical cancer and 22/26 patients with nasopharynx cancer achieved CR. Among 15 patients with palliative therapy, 80% achieves palliation. We will describe the details of the technique and results in the text. To evaluate biologic effects of HDRB and optimal time/dose/fractionation schedule, we need longer follow-up. But authors feel that HDRB with proper fractionation schedule may yield superior results compared to the low dose rate brachytherapy considering the advantages of HDRB in safety factor for operator, better control of radiation dose and volume and patients comfort over the low dose brachytherapy.

Abnomalities in the production and transport of airway secretions play an important role in the pathophysiology of asthma. Segmental atelectasis as a complication of asthma, is relatively common in children. On the other hand, massive atelectasis such as the collapse of one lung is a very rare occurence. We report a seven-year-old male asthmatic patient with right lung collapse caused by mucoid impaction. Fourteen months before admission, the patient experiened bronchopneumonia with left unilateral lung collapse due to mucus plugging and recovered by bronchoscopic removal. The clinical findings, chest X-ray and chest CT suggested the collapse of the right lung was caused by mucus plugging. Fiberoptic bronchoscopy revealed the obstruction of the right main bronchus due to thick mucoid impaction. The histologic finding of mucoid material removed by brochoscopy showed only eosinophil clusters. In addition to fibroptic broncoscopic removal of mucoid secretions, hydration, chest physiotherapy, brochodilators and steroids, the patient received tracheostomy because of difficulty in sputum expectoration, poor improvement of clinical symptoms and chest X-ray findings, with rapid improvements. This case showed that early aspiration of bronchial mucoid secretions by bronchoscopy and tracheostomy was very critical, without waiting for a further deterioration of respiratory function.
