- Abstract
Background: Many factors influence young women's choice of contraceptive methods and where to source them, yet less is known about whether one of these choices (method or source) is prioritized and the relationship between these choices. This study qualitatively explored decision-making around contraceptive method and source choice among young women in Kenya., Methods: In August-September 2019, 30 in-depth interviews were conducted with women ages 18-24 who had used two or more contraceptive methods and resided in three counties: Nairobi, Mombasa or Migori. Participants were recruited from public and private health facilities and pharmacies. Interview guides captured information about decision-making processes for each contraceptive method the respondent had ever used. Responses were audio-recorded, transcribed, translated into English, coded, and analyzed thematically., Results: The majority of respondents knew which method they wanted to use prior to seeking it from a source. This was true for all types of methods that women ever used. Of the small number of respondents who selected their source first, most were in the post-partum period or experiencing side effects and sought counseling at a source before choosing a method., Conclusions: This study highlights the importance of providing young women with high quality counseling that provides full information about contraceptive options and addresses that young women's needs vary along the reproductive health continuum of care. This will ensure that young women have information to inform future contraceptive decision-making prior to seeking care., (© 2023. The Author(s).)

- Abstract
Background: Many young women experience important key life transitions during adolescence and early adulthood, such as initiation of sexual activity, first use of contraceptives, marriage, and childbirth. For young women to be able to plan and manage their lives, it is critical to understand how these life events intersect and shape their contraceptive decision-making. This study aims to explore young women's contraceptive method use trajectories, including the factors that influence contraceptive decision-making throughout adolescence and youth., Methodology: In 2019, the Full Access, Full Choice project (FAFC), implemented by the University of North Carolina at Chapel Hill and the African Institute for Development Policy, conducted 30 in-depth interviews with young women aged 18-24 years in three counties in Kenya (Nairobi, Mombasa and Migori). Eligible respondents had used two or more modern contraceptive methods. Interview guides utilized a modified life history approach to capture details about respondents' contraceptive use and life experiences from the time they first used contraception until the time of interview., Results: We identified five separate contraceptive use trajectories based on the occurrence and timing of marriage, childbirth, and contraceptive method choice as well as various influences on contraceptive decision-making. The majority of respondents began their contraceptive journey by using male condoms or emergency contraception, but subsequent contraceptive decisions were varied across trajectories and influenced by different factors. For many women, the initiation of a non-coitally dependent method occurred after the birth of a child; for some, this was the first method used. Once women transitioned to using a non-coitally dependent method such as injectables or implants, many cycled through different methods to find one that had fewer side effects or provided the desired duration of protection., Discussion: This study highlights the nuanced needs of young women throughout their adolescent and youth years in Kenya. This suggests that programs and policies need to encompass young women's diversity of experiences and motivations to best serve them., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Calhoun, Mandal, Onyango, Waga, McGuire, Zulu, van den Akker, Benova, Delvaux and Speizer.)

- Abstract
Cervical cancer has a high incidence and mortality rate in low- and middle-income countries (LMICs) largely due to limited resources and insufficient staffing. Knowledge-based planning (KBP) could alleviate understaffing issues by streamlining the radiotherapy treatment planning process. Varian's KBP system (RapidPlan) was used to develop a model capable of producing volumetric modulated arc therapy (VMAT) plans for cervical cancer patients. Plan data from 46 patients previously treated at MD Anderson Cancer Center (MDACC) were used to create and train the model which was then applied to 32 patients excluded from the training process. Dose volume histogram (DVH) values for the planning target volume (PTV_High), bladder, rectum, and bowel were evaluated for the validation plans and found to have satisfied the required PTV coverage and organ-at-risk (OAR) dose constraints. The average value for PTV_High D
95.0% was 48.0 Gy (sd = 3.0 Gy) for existing clinical plans and 48.4 Gy (sd = 2.6 Gy) for the validation plans. The mean dose for the bladder, rectum, and bowel was 39.8 Gy (sd = 3.9 Gy), 41.6 Gy (sd = 5.2 Gy), and 21.6 Gy (sd = 5.0 Gy) for existing clinical plans and 38.9 Gy (sd = 4.0 Gy), 40.3 Gy (sd = 4.8 Gy), and 21.5 Gy (sd = 4.6 Gy) for validation plans, respectively. A TOST test showed that the p values for the PTV_High D95.0% (p < 0.001), rectum V30Gy (p = 0.039), and mean dose to the bladder (p = 0.0014), rectum (p = 0.025), and bowel (p = 0.006) were statistically significant within a 5% equivalence margin of the clinical value thereby providing strong evidence of equivalence. Based on this statistical analysis, it was determined that the model was capable of generating treatable VMAT plans for cervical cancer patients., Competing Interests: Declaration of Competing Interest Dr. L.

- Abstract
We report a case of asynchronous bilateral neuroendocrine breast carcinoma. The patient was a 49-year-old woman presenting with a bloody nipple discharge from the right breast. We suspected intraductal papilloma and performed a microdochectomy. A pathological analysis of the resected specimen confirmed the diagnosis as neuroendocrine carcinoma. The tumor was positive for estrogen receptor, progesterone receptor, chromogranin A, and synaptophysin, but negative for the HER2/neu marker. The Ki-67 labeling-index was 40%. As the tumor margin was positive, breast-conserving surgery plus level II axillary lymph node dissection was performed. After surgery, radiotherapy(total dose of 50 Gy)was administered for treating residual breast involvement. Adjuvant hormonal therapy was performed for 5 years. Ten years after surgery, ultrasonography revealed a 12mm irregular hypoechoic mass in the left breast. The mass was diagnosed as a solid tubular carcinoma based on core needle biopsy findings. Subsequently, we performed breast-conserving surgery. The pathological diagnosis was a neuroendocrine carcinoma, and the tumor was positive for estrogen receptor, progesterone receptor, chromogranin A, synaptophysin, and CD56, but negative for the HER2/neu marker. The Ki-67 labeling-index was 50%. We report our experiences with a rare case of asynchronous bilateral neuroendocrine breast carcinoma. In this case, ultrasonography was a useful modality for detecting both the lesions.

- Abstract
We report a case of primary advanced breast cancer that was locally controlled by treatment with bevacizumab. A 69-yearold woman presented at our hospital complaining of left breast hemorrhage. Her left breast had a large mass with an ulcer, and there was bleeding. Breast ultrasonography showed a large tumor that involved the whole left breast, and some swollen axillary lymph nodes. Breast MRI showed a mass of 77mm and skin invasion around the medial area of the left breast. Histopathological examination indicated invasive ductal carcinoma, ER(+), PgR(+), HER2(-), Ki-67 20%. We diagnosed left breast carcinoma, T4bN1M0, stage III B. She received paclitaxel plus bevacizumab as first-line therapy. Breast MRI showed a reduction in the primary tumor and axillary lymph node swelling. Adverse events including hypertension(Grade 3) and peripheral neuropathy(Grade 2)were observed. She received letrozole as second-line therapy. After commencing letrozole, the tumor reduced further, and the local ulcer disappeared showing only induration. Four years from the start of treatment, the woman has obtained good local control and has not developed other metastases.

- Abstract
We experienced 2 cases in which eribulin mesylate was effective for taxane-resistant advanced breast cancer. Case 1: A 65- year-old woman was diagnosed with advanced breast cancer(T4cN2aM0, stage III B)and treated with chemotherapy(nabpaclitaxel). Bone metastasis was observed; then, she sequentially received epirubicin and cyclophosphamide, nab-paclitaxel, and bevacizumab and paclitaxel. However, lung metastases appeared, and we changed the regimen to eribulin mesylate. We administered 11 courses of eribulin mesylate before bone marrow metastasis appeared. Eribulin mesylate was effective for more than 1 year. Case 2: A 77-year-old woman was diagnosed with advanced breast cancer(T4bN3cM1, stage IV), and liver and pleural metastasis were observed during an examination at the first visit. Four courses of nab-paclitaxel were administered, but because of the increase in pleural effusion, we changed the regimen to eribulin mesylate. Thirteen courses of eribulin mesylate were administered before the disease progressed. The progression-free survival was 9.53 months. Through the 2 cases in which eribulin mesylate was effective for taxane-resistant advanced breast cancer, the effect of eribulin mesylate compared to taxane was clinically inferred.

- Abstract
A 73-year-old man with a suspected ileus in January 2013 and subsequently suffered melena in February 2014 was endoscopically examined. As a result of the examinations, unidentified species of Corynosoma sp. and Corynosoma villosum were recovered from the small intestine, further endoscopic diagnosis suggested relevance between abdominal pain and the present infections in the small intestine. The recovered worms were composed of gravid females with developed eggs, suggesting that these parasites can survive for a long time in the intestine after infection. In this case, the short interval between infections appears to be due to the individual's eating habits which consist of regularly consuming uncooked seafood., (Copyright © 2016 Elsevier Ireland Ltd.

- Abstract
Background and Study Aims: Sodium phosphate is a key component of bowel preparation regimen for colon capsule endoscopy (CCE), but may cause serious complications. The aim of this study is to evaluate the use of Gastrografin, substituted for sodium phosphate, in CCE bowel preparation., Patients and Methods: In total, 29 patients (median age 64 years; 23 females) underwent CCE, covered by the national health insurance system of Japan. All had a history of laparotomy and/or previously incomplete colonoscopy. On the day before examination, patients ingested 1 L of polyethylene glycol + ascorbic acid with 0.5 L of water in the evening, and again the same laxative on the morning of examination. After capsule ingestion, 50 mL of Gastrografin diluted with 0.9 L of magnesium citrate was administered, and then repeated after 1 hour., Results: The capsule excretion rate was 97 % (28/29). The median colon transit time was 2 hours 45 minutes and rapid transit (< 40 minutes) through the colon occurred in one patient (3.4 %). Bowel cleansing level was adequate in 90 % of patients. The polyp (≥ 6 mm) detection rate was 52 %. Diluted Gastrografin was well tolerated by patients. No adverse events occurred., Conclusion: Gastrografin can be an alternative to sodium phosphate in CCE bowel preparation regimen.

- Abstract
We examined the records of patients with stage Ⅳ breast cancer who underwent primary tumor resection after systemic therapy. In our department, in 2013, there were 8 such cases. The average local tumor diameter was 59 mm. There was 1 case of metastases to the liver, 2 cases to the lung, 3 cases to the bone, and 1 case to the kidney. Three cases had lymph node metastases. Two cases were treated with hormonal therapy, and 6 cases received chemotherapy as preoperative systemic therapy. All cases underwent Bt plus Ax. Approximately 2 years after the surgery, 5 of the 8 patients were alive. The postoperative local control was good and we were able to continue systemic treatment for the distant metastases in all cases. We think that resection of the primary tumor improved the quality of life of the patients. However, for 1 fatal case, a brain metastasis was detected shortly after surgery. Therefore, we need to consider the patient's condition carefully before we operate.

- Abstract
The use of endoscopic submucosal dissection (ESD) for duodenal neoplasms has increased in recent years, but delayed perforation and bleeding are also known to frequently occur. We present two cases in which duodenal adenoma was successfully treated with laparoscopic-endoscopic cooperative surgery. ESD was combined with laparoscopic seromuscular sutures. The lesions in both cases were located in the second portion of the duodenum. The patients requested resection of the lesion, and we performed laparoscopic-endoscopic cooperative surgery. After the laparoscopic surgeon mobilized the duodenum, the endoscopic surgeon performed ESD for the duodenal tumor without perforation. The laparoscopic surgeon sutured the duodenal wall in the seromuscular layer to strengthen the ulcer bed after ESD. Histopathological studies confirmed that the surgical margins were tumor-free in both cases. The patients were discharged with no complications. This unique laparoscopic-endoscopic cooperative procedure is a safe and effective method for resecting superficial nonampullary duodenal tumors., (© 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.)

- Abstract
We report a case in which we were able to treat multiple tumors in the right breast with breast-conserving surgery. The patient was a 60-year-old woman in whom mammography revealed grouped round calcifications and distortion in the right breast. The tumor was not palpable. Ultrasonography revealed 3 tumors in the patient's right breast. One tumor, 14.5 mm in diameter, was located in the AC area of her right breast. Vacuum-assisted core-needle biopsy was performed on this tumor, and histopathological examination revealed invasive ductal carcinoma of the breast. The tumor was estrogen receptor (ER)-positive, progesterone receptor( PgR)-negative, and human epidermal growth factor receptor( HER)-2-positive. Another tumor, 5.5 mm in diameter, was located in the C area of the patient's right breast. This tumor was diagnosed as a satellite lesion of the tumor in the AC area. The third tumor, 19.0 mm in diameter, was located in the A area of the patient's right breast. This tumor was expected to be a fibroadenoma on the basis of the clinical findings. We performed breast-conserving surgery to remove these 3 tumors and biopsied the sentinel lymph nodes. Intra-operative rapid pathological diagnosis indicated that the surgical margins were negative and the sentinel lymph nodes were negative for metastasis. The final pathological diagnosis was the same as the preoperative diagnosis.

- Abstract
Case 1: Case 1 involved a 42-year-old woman who had been diagnosed as having advanced breast cancer (Stage III B). She had previously received 6 courses of cyclophosphamide, epirubicin, and 5-fluorouracil CEF, 14 courses of weekly paclitaxel, and 2 courses of vinorelbine( VNR). After the courses of chemotherapy, she underwent modified radical mastectomy with axillary lymph node dissection. Two years after surgery, lung metastases were found, and the patient received 6 courses of weekly paclitaxel and 13 courses of nab-paclitaxel. However, the lung metastases progressed after the courses of chemotherapy, and therefore, we decided to administer eribulin as third-line chemotherapy. Eribulin was effective against the lung metastases for more than 1 year. Case 2: Case 2 involved a 52-year-old woman who had been diagnosed as having Stage IIB breast cancer. She had received 4 courses of CEF and 4 courses of docetaxel as neo-adjuvant chemotherapy. After chemotherapy, she underwent breast-conserving surgery with axillary lymph node dissection. Five years postoperatively, multiple liver metastases were found, and the patient received 3 courses. However, the liver metastases progressed after this chemotherapy. Subsequently, we administered nab-paclitaxel; however, it produced severe side effects. We then decided to administer eribulin as second-line chemotherapy. Eribulin was effective against the liver metastases for more than 1 year.

- Abstract
We report a case of combined noninvasive ductal and lobular carcinoma. The patient was a 54-year-old woman with a breast tumor. The tumor was a palpable movable mass measuring 1 cm in diameter in the AC region of her breast. Mammography, ultrasonography, magnetic resonance imaging, and vacuum-assisted core-needle biopsy were performed. The histopathological diagnosis was intraductal papillary cystic lesion. However, there was also a ductal lesion. We performed lumpectomy, and the diagnosis was combined noninvasive ductal and lobular carcinoma. It was difficult to determine the range of carcinoma, and thus, we performed Bt+Ax. Combined noninvasive ductal and lobular carcinoma is rare. We should study additional cases and develop more adequate treatments.

- Abstract
The patient was a 58-year-old woman. Mammography showed grouped heterogeneous calcifications in the M area of the right breast. The area of the grouped heterogeneous calcifications was 1 cm in diameter. A vacuum-assisted biopsy (VAB) of the area led to a diagnosis of invasive ductal carcinoma positive for estrogen receptor and progesterone receptor, and negative for human epidermal growth factor receptor type 2/neu protein expression. A micro mark was made by VAB enforcement in the lesion. At operation, we performed ultrasonography to detect the cancer lesion, but we could not detect the micro mark. It was difficult to determine the resection area. We detected architectural distortion after VAB and determined the resection area. Breast-conserving surgery and a sentinel lymph node biopsy was performed. Histopathologically, the surgical margins were negative and the sentinel lymph node was negative for cancer. This case suggested that it was necessary to make a new micro mark.

- Abstract
We compared the surgical margins for phyllodes tumors of the breast required for endoscopic local excision and normal local excision. Over a 10-year period, we experienced 38 patients with phyllodes tumors of the breast who were treated by surgical operation. Thirty-three patients underwent local excision with a surgical margin of at least 1.0 cm, and 5 underwent endoscopic local excision with a surgical margin of at least 1.0 cm. The pathological surgical margins were negative in all patients. The surgical margins for both endoscopic local excision and normal local excision were almost identical. However, the surgical wounds caused by endoscopic local excision were smaller than those caused by normal local excision. These results suggest that endoscopic local excision is a useful method for phyllodes tumor.

- Abstract
We report a case of breast cancer with lymph node metastases. A complete response was recognized in response to nab-paclitaxel as a first-line therapy after recurrence. The patient was a 50-year-old woman who had a tumor in her right breast. We palpated a mass with clear boundaries in her right breast. The tumor was 2 cm in diameter. Core-needle biopsy of the breast tumor led to a diagnosis of invasive ductal carcinoma (estrogen receptor-, progesterone receptor-, and human epidermal growth factor receptor 2-negative). She received 4 cycles of EC (E: 90 mg/m2/tri-weekly; C: 600 mg/m2 /tri-weekly) plus 4 cycles of TC(T: 75 mg/m2/tri-weekly; C: 600 mg/m2/tri-weekly)as preoperative adjuvant chemotherapy. After chemotherapy, she underwent quadrantectomy plus axillary lymph node dissection. Six months after the operation, lymph node metastases were observed in her right supraclavicular lymph nodes. She received 8 cycles of nab-paclitaxel(260 mg/m2/tri-weekly) therapy. After 8 cycles of treatment, ultrasonography and computed tomography revealed the disappearance of the metastatic lymph nodes. Therefore, a clinical complete response was observed.

- Abstract
A 55-year-old woman underwent segmental resection and sentinel lymph node biopsy for cancer in her left breast 2.5 years ago. The pathological findings indicated papillotubular carcinoma [estrogen receptor-positive (ER+), progesterone receptor-positive(PgR+), and human epidermal growth factor receptor 2(HER2) score 0]. After the operation, she received adjuvant radiotherapy and endocrine therapy. Two and a half years after the operation, mammography revealed amorphous calcifications in her right breast. Stereotactic directional vacuum-assisted core-needle biopsy of the calcifications led to a diagnosis of invasive ductal carcinoma (ER+, PgR+, HER2 score 0). We performed quadrantectomy and sentinel lymph node biopsy. After the second operation, she received adjuvant radiotherapy and endocrine therapy with different modalities than used previously. Since the second operation, there has been no metastasis or recurrence.

- Abstract
A 64-year-old woman was introduced to our hospital with liver tumors. Our examination revealed that she had advanced colon carcinoma with multiple liver metastasis. Without symptoms from the primary cancer, she underwent chemotherapy of avastin FOLFOX. After 2 courses of chemotherapy, she suffered ileus and underwent operation. The resected specimen showed marked tumor necrosis and fibrosis, but few tumor cells remained in the primary lesion. We think this was a rare case of suffered ileus because of marked response of chemotherapy in primary colon carcinoma.

- Abstract
Mesalamine has been used as the first-line therapy for the treatment of ulcerative colitis (UC) because of its efficacy and fewer side effects. However, earlier study showed that mesalamine occasionally causes diarrhea. We are presenting a patient with active UC in whom bloody diarrhea accompanied by abdominal pain and fever occurred and the symptoms were aggravated after administration of mesalamine. In order to clarify the reason of symptoms aggravation, drug lymphocyte stimulation test and rechallenge trial with mesalamine were performed. The results indicated the possibility that aggravation was related to allergic reaction and was dose-dependent. Furthermore, we examined colonoscopic views but there was no remarkable change in before and after rechallenge trial. Based on the above result, the patient was diagnosed with mesalamine intolerance. In order to differentiate whether the exacerbation of bloody diarrhea is due to the side effects of the mesalamine or a true relapse of UC, taking careful history before and after increasing mesalamine dosage as well as being aware of side effects of mesalamine are required. Clinicians should be aware of diarrhea as a side effect of mesalamine particularly after onset of mesalamine formulation, change in mesalamine formulation, or change in mesalamine dose.

- Abstract
Context: An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor which was first described by Adsay et al. in 1996. It has been defined as a new subgroup of IPMN., Case Report: We report the case of a 76-year-old woman who presented with nausea. Imaging studies revealed a cystic mass in the body of the pancreas. She underwent a successful distal pancreatectomy and splenectomy, and has subsequently remained well. Microscopically, the cyst was lined by columnar epithelium similar to pancreatic duct epithelium, and the nodular projection consisted of arborizing papillary structures, lined by plump cells with abundant eosinophilic cytoplasm. These eosinophilic cells were immunohistochemically positively stained with anti-mitochondrial antibody. The cellular atypism was mild and the proliferating index was low, compatible with adenoma of an intraductal oncocytic papillary neoplasm. Although no ovarian type stroma was identified, in our case, no communication to main pancreatic duct (located in the pancreatic body) and rapid growth by intracystic hemorrhage were clinical characteristics of a mucinous cystic neoplasm, but not IPMN., Conclusion: With only 17 cases reported to date, the clinical and pathological details of an intraductal oncocytic papillary neoplasm are still unclear. We herein add one case with different characteristics from those of the past reports. To our knowledge, this is the first case report of an intraductal oncocytic papillary neoplasm with the clinical characteristics of a mucinous cystic neoplasm.

- Abstract
Background: Acute hemorrhagic rectal ulcer (AHRU) has increasingly been reported in Japan, whereas it has rarely been reported in the English literature and is not yet established as a disease entity. The aim of this study was to elucidate clinical and endoscopic characteristics of patients with AHRU., Methods: We enrolled 20 patients with 26 ulcers diagnosed as AHRU in our department between January 2001 and October 2005. Clinical features such as the underlying disorder, Karnofsky performance status (PS), and presence or absence of anticoagulant or antiplatelet therapy, as well as endoscopic findings and type of bleeding, were evaluated. Strategies for hemostasis were also reviewed., Results: The most prevalent underlying disorder was diabetes mellitus, and the number of bedridden patients with PS 4 was relatively high. In addition, more than half of the patients had been treated with anticoagulant or antiplatelet agents. Endoscopically, ulcers were characteristically solitary and irregularly shaped, and they did not show any typical localization pattern. As a hemostatic strategy, clipping alone showed a favorable result, with a hemostatic success rate as high as 76.9%., Conclusions: This study may support the establishment of AHRU as a new clinical entity. In aged patients being treated with anticoagulant or antiplatelet agents, especially bedridden patients using aspirin, the possible appearance of this disease should be kept in mind.

- Abstract
Cholangitis and pancreatitis associated with cytomegalovirus (CMV) infection in an immunocompetent patient is reported. Endoscopic retrograde cholangiography performed on a 55-year-old man for evaluation of the cause of jaundice and liver dysfunction revealed a distal focal irregular narrowing of the common bile duct. Microscopic findings of the resected specimen showed chronic cholangitis and CMV pancreatitis. Immunohistochemistry disclosed that epithelial cells in the inflamed bile duct were positive for CMV antigen, which was compatible with CMV cholangitis. Inflammation of the biliary tract or pancreas by CMV has been commonly reported as a complication in immunocompromised patients. Our report appears to be a rare case, but suggests that CMV cholangitis or pancreatitis should be considered in the differential diagnoses of common bile duct stenosis or pancreatitis even in immunocompetent individuals.

- Abstract
The patient was a 68-year-old woman who visited a nearby clinic with a chief complaint of right hypochondrial pain. A mass lesion in the gallbladder was found by ultrasonography. She was referred to our hospital for further examination and was diagnosed with gallbladder cancer. Cholecystectomy and bile duct resection were performed. Six months after the surgery, multiple liver metastases were found. A subcutaneous implant reservoir was placed in the hepatic artery from the right femoral artery. After arterial infusion chemotherapy by 5-FU and CDDP, or 5-FU alone, liver metastasis markedly responded and became undetectable, and therapy was therefore discontinued. The patient has been disease-free without any sign of recurrence for 7 months after CR was achieved. It is suggested that arterial infusion chemotherapy is useful and safe for the treatment of liver metastasis from gallbladder cancer.
