Paraneoplastic neurologic degeneration (PND) manifests as a sudden or subacute neurological syndrome often linked to underlying cancer, either overt or subclinical. Within the spectrum of PND, subacute paraneoplastic cerebellar degeneration (PCD) represents a distinctive subset. While rare, prompt diagnosis holds the potential to ameliorate both neurological and oncological outcomes. Herein, we present the case of a 61-year-old patient diagnosed with subacute cerebellar degeneration, ultimately unveiling non-small cell lung carcinoma.

OBJECTIVE: Uterine fibroids increase the risk of preterm birth. The current study highlights uterine fibroid necrosis as a possible cause of (extreme) preterm birth.
METHODS: Retrospective cohort study in one Dutch academic hospital. Cases were selected from the 526 participants of the MyoFert study (Netherlands Trial Register, NL7990), which included patients who presented between 2004 and 2018 and were between the age of 18 and 45 years at the time of diagnosis of uterine fibroids. Of these participants, 414 women became pregnant. A retrospective chart review of the first pregnancies was performed. The main outcomes were (imminent) preterm birth and signs of fibroid necrosis on ultrasound. In women with signs of fibroid necrosis, the following data were collected systematically: fibroid characteristics, clinical presentation, pregnancy outcome, and postpartum period.
RESULTS: In total, 66 women had a preterm birth (16 %, 66/414), of which 25 pregnancies ended between 16 and <24 weeks (38 %, 25/66) and 41 pregnancies ended between 24 and <37 weeks of gestation (62 %, 41/66). Of all women with preterm birth and available ultrasound images, 15 % (7/48) had fibroid necrosis at the time of labour. These seven patients, supplemented with three patients with fibroid necrosis during their first pregnancy and at least one episode of imminent preterm birth, are described in more detail. In these ten patients, the fibroids increased substantially in size during the first and second trimester, leading to severe abdominal pain in all patients and hospital admission in seven patients. Ultrasound examination of the fibroids showed heterogenic changes and focal transonic areas in the fibroid, which are characteristics that indicate fibroid necrosis. In four patients, myomectomy was performed and necrosis was confirmed histologically.
CONCLUSIONS: Fibroid necrosis during pregnancy is likely associated with (imminent) preterm birth. Clinicians are advised to structurally evaluate the myometrium in pregnancy, specifically in women presenting with abdominal pain in the second trimester.

Primary umbilical neoplasms are exceptionally rare. Neurofibromas histologic findings vary from collagenous to myxoid matrix according to the neoplastic elements differentiation. We present a case of neurofibroma in the supraumbilical region undergoing cystic myxomatous degeneration. A 75-year-old female presented to the department with a complaint of swelling above the umbilicus for the last three years. The swelling was excised and grossly was a single, irregular, reddish-yellow cystic mass measuring 4.5 × 4 x 3 cm. On the cut section, cystic jelly-like areas were identified, and histopathological features were suggestive of neurofibroma undergoing cystic myxomatous degeneration. The diagnosis needed to be combined with pathological examination, and careful consideration during the surgical intervention was important to confirm there was no residue.

Pseudo broad ligament fibroids originate in the uterus but grow into the broad ligament while retaining their attachment to the uterus. We report a case of a right-sided pseudo broad ligament fibroid mimicking an adnexal mass in a 40-year-old woman presenting with dysmenorrhoea and heavy menstrual bleeding. She had a uterine mass corresponding to an 18-week pregnant uterus size, which clinically and radiologically posed a diagnostic dilemma between an ovarian cyst, a bicornuate uterus with multiple fibroids, and a broad ligament fibroid. She underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy, which revealed a pseudo broad ligament fibroid of 12x10x6 centimeters, weighing 1.2 kg. The histopathology report confirmed the diagnosis of a leiomyoma with normal ovaries.

UNASSIGNED: Leiomyoma is the most common gynecologic tumor which may show atypical locations and degenerations. Cystic degeneration is said to be found in 4 % of all degenerations. Endometriosis, the presence of endometrial glands and stroma at extrauterine sites, is a common gynaecological condition seen in 10 % to 15 % of reproductive-age women usually being associated with various degrees of fertility problems.
METHODS: 40 years old woman with P1L1A2, with secondary sub-fertility for 5 years, presented with chief complaints of dysmenorrhoea for 1 year initially around the menstrual cycle relieving with analgesics but later not limited to the menstrual cycle and pain not relieving with analgesics since 1 month. The patient underwent fertility-sparing laparoscopic removal avoiding a laparotomy and definitive hysterectomy. Manual morcellation was achieved.
UNASSIGNED: Cystic degeneration is rare in Leiomyoma although it is the more common gynaecological tumor in women and is associated with endometriosis probably due to retrograde menstruation.
CONCLUSIONS: Laparoscopic removal of leiomyoma without laparotomy and definitive hysterectomy for a case of cystic endometriosis in a degenerated subserous myoma which to the best of our knowledge according to our search of articles on the relevant topic is the first reported case pertaining to the topic from Nepal.

In the foot, the lumbricals flex the metatarsophalangeal joints and extend the interphalangeal joints. The lumbricals are known to be affected in neuropathies. It is not known whether they may degenerate in normal individuals. Here, we report our findings of isolated degenerated lumbricals in seemingly normal feet of two cadavers. We explored lumbricals in 20 male and 8 female cadavers that were 60-80 years of age at the time of death. As part of routine dissection, we exposed the tendons of the flexor digitorum longus and the lumbricals. From the degenerated lumbricals, we took some tissue for paraffin-embedding, sectioning, and staining by hematoxylin and eosin, and Masson\'s trichrome technique. Of the 224 lumbricals studied, we found four apparently degenerated lumbricals in two male cadavers. In the first, the 2nd and 4th lumbricals in the left foot and the 2nd in the right foot were degenerated. In the second, the right 4th lumbrical was degenerated. Microscopically, the degenerated tissue was made of bundles of collagen. The lumbricals may have degenerated due to compression of their nerve supply. We cannot comment on whether the functionality of the feet were affected by these isolated degeneration of the lumbricals.

The pleomorphic adenoma is a benign tumor. The patient was 55 years old, with no particular pathological history. For 18 months, she had a progressive and permanent right nasal obstruction associated with intermittent epistaxis, rhinorrhea and chronic unilateral tearing. The nasofibroscopy showed a smooth reddish bleeding tumor of the right nasal cavity, reaching the lower part of the middle cornet. Oropharynx examination revealed on the right side a sessile and bulging tumor of the palate with respect of the mucosa, the tumor goes through the choanae into the oropharynx. The CT scan showed a large aggressive lesion process centered on the right nasal cavity with bone lysis of the posterolateral wall of the maxillary sinus and invasion of the infratemporal fossa. MRI showed a maxillary right naso-sinusal tumor process infiltrating the ethmoidal cells, the right infratemporal fossa with endobuccal extension and filling the nasopharyngeal lumen. The patient was operated through the right external para-latero-nasal, associated to an endonasal abord. Anatomo-pathological with immune-histochemical study was performed to ensure complete removal of the tumor and it showed a high grade cystic adenoid carcinoma.

This research aims to study possible effects or impacts of COVID-19 in the context of a democratic organizational system analyzing how COVID-19 has influenced employees\' perception of their participation in decision-making and its impact on some psychological outcomes and emotions. COVID-19 has accelerated the process of implementation of new frameworks at work (digitalization, teleworking, new skills, and abilities) that have generated the modification of culture and employee management practices. Our hypothesis are, on the one hand, that COVID-19 has generated changes in participation structures and internal communication mechanisms, having to make modifications not to deteriorate the perception of employees about their participation in decision making. On the other hand, COVID-19 has generated changes in the psychological outcomes and emotions of the employees. In the study, we analyze a cooperative belonging to the MONDRAGON cooperative group, where participation in decision-making and ownership is in its DNA. Through qualitative (5 focus groups) and quantitative (short questionnaire) methodologies, involving 42 employees, we investigate firstly, how COVID-19 has affected perceptions about participation in decision-making analyzing what role has played internal communication in these perceptions. Secondly, we investigate how COVID-19 has affected psychological outcomes and emotions. In this case, the perceptions arising from participation in decision-making focus on the assessment that participators make of the governance channels and the day-to-day meetings. Therefore, their appropriateness seems to be a key factor in the perception of participation in the COVID-19 era. Differences have been detected between the perceptions of blue and white collar employees. Such differences have also been founded in the psychological outcomes and emotions. Although this is a single case study, the analysis carried out provides elements of reflection to modify and restructure the decision-making and participation mechanisms, adapting them to the needs of blue and white collar employees in order to \"guarantee\" the expected outcomes.

We report a case of segmental arterial mediolysis (SAM) that involved the middle colic artery, and present some pathologic alterations found in mesenteric small arteries and veins. The patient, a 52-year-old woman, underwent an emergency laparotomy for acute intra-abdominal hemorrhage, and a segment of the transverse colon with hemorrhagic mesocolon was excised. Microscopic examination demonstrated two separate lesions of SAM in the middle colic artery. The involved arterial segments showed a partial to circumferential loss of the media (mediolysis) and intima associated with the formation of a pseudoaneurysm. Smooth muscle cells adjacent to the mediolysis showed various degenerative changes. In addition, we found multiple, tiny foci of degenerative lesions affecting the outer media in the wall of small arteries. Subendothelial vacuoles and nodular intimal proliferation were also noted in small veins. Whereas SAM chiefly affects large or medium-sized arteries, small blood vessels, including veins, are also affected. The present case is unusual in that degeneration of medial smooth muscle cells was clearly observed in the arterial walls, and the small veins were affected by lesions similar to those in arteries. We suspect that a phenotypic modulation of vascular smooth muscle cells induced by some genetic vulnerability plays a role in the pathogenesis of SAM.

Sporadic inclusion body myositis (IBM) is a chronic inflammatory and degenerative muscle disease with limited treatment options; no therapy can alter its natural course. Ketogenic diets are theoretically capable of suppressing inflammation, enhancing cell bioenergetics, alleviating mitochondria dysfunction, and stimulating autophagy, which may be beneficial in IBM. We report the case of a 52-year-old woman with worsening IBM who pursued a modified ketogenic diet for 1 year. Adverse effects were mild and resolved 3 weeks into the diet. Prior to starting her ketogenic diet, despite the use of a walking stick at all times, she was experiencing one to two falls per week as well as swallowing difficulties, musculoskeletal pain, and depression. Moreover, magnetic resonance imaging (MRI) of the bilateral thighs during the year prior to the diet indicated worsening muscle inflammation and a 14% decrease in thigh muscle volume, which corresponded to a 4% decrease in the ratio of thigh muscle to thigh total volume. After 1 year on her ketogenic diet, our patient regained independent walking, and her swallowing difficulties, pain, and depression resolved. She maintained her strength, improved in every test of function, enhanced her quality of life, and lowered her blood creatine kinase. MRI of the bilateral thighs during the year of the diet indicated stabilized muscle inflammation and a 2.9% decrease in thigh muscle volume, which in the context of diet-induced fat loss corresponded to a sustained 1% increase in the ratio of thigh muscle to thigh total volume. This case is unique in that a ketogenic diet was utilized as the primary treatment strategy for a patient with confirmed IBM, culminating in substantial clinical improvement, stabilized muscle inflammation, and a slowed rate of muscle atrophy. Our patient has remained on her ketogenic diet for over 2 years now and continues to enjoy a full and independent life.
