Resolution of painful trichodysplasia spinulosa with topical cidofovir: case report

Purpose: Trichodysplasia spinulosa (TS) is a rare, disfiguring skin condition which presents with widespread asymptomatic or pruritic, skin-colored papules with white protruding keratin spiculations in immunocompromised individuals. Due to its rarity, there is little data to guide treatment decisions. The purpose of this article is to report a case of TS that completely resolved after treatment with topical cidofovir.Materials and methods: A 19-year-old immunosuppressed female presented with widespread painful, itchy bumps on the nose and face. Upon examination, there were erythematous papules with hyperkeratinized spicules affecting the central face. Biopsy of the lesions was consistent with TS which was confirmed via PCR analysis. The tenderness of this patient's eruption was highly atypical for TS. Once daily topical application of compounded 1% cidofovir cream was prescribed.Results: The patient's symptoms resolved completely after 4 weeks of therapy with topical cidofovir 1% cream, without reduction of immunosuppression.Conclusions: Topical cidofovir 1% cream may be a valuable treatment for this rare disease.

Hematological investigations in a case of intravascular hemolysis due to Clostridium perfringens infection

A patient presented with fever, severe pain and edematous tight due to hip trauma and was scheduled for urgent fasciotomy. Following physical examination, laboratory analyses were requested, and results revealed anemia and severe infection. As the patient's condition was serious, a new set of samples was sent to the laboratory four hours later. Following centrifugation, severely hemolyzed dark-colored serum and plasma samples were obtained and in vitro hemolysis was suspected. The collection of samples was repeated, but a new set of samples was also hemolyzed with a significant decrease in the hemoglobin value. At that point, in vivo hemolysis was suspected, and samples were processed according to standard laboratory procedures for hemolytic samples. Following confirmation of the gas gangrene diagnosis by clinicians, the cause of hemolysis was attributed to the cytotoxic activity of α-toxin produced by the anaerobic gram-positive bacterium Clostridium perfringens. An insight into the laboratory procedure that could help to narrow down the causes of hemolysis and single out C. perfringens as a cause of intravascular hemolysis was given.

Primary anastomosing hemangioma as a preoperative diagnostic mimicker of retroperitoneal cavernous hemangioma: A case report

Anastomosing hemangioma (AH) is rare and a newly recognized variant of capillary hemangioma that is mostly found in the genitourinary tract. Additionally, AH is sometimes difficult to diagnose without pathological specimens. It is difficult to diagnose preoperatively due to the lack of specific clinical and radiologic appearance. The present report describes the imaging features from a radiological perspective and outlines the clinicopathologic features and treatment options. A 67-year-old woman was referred to Dokkyo Medical University Saitama Medical Center (Koshigaya, Japan) for a retroperitoneal tumor that was identified at a medical checkup 4 years prior. The patient had no symptoms, no abnormal physical signs and no past medical or specific family history. Routine blood tests were all within the normal ranges. A nonenhanced CT scan showed a circular, homogenous, well-circumscribed retroperitoneal tumor that was ~32×23 mm in size, between the abdominal aorta and the inferior vena cava, and just below the left renal vein. On a contrast-enhanced multidetector CT scan, the tumor showed heterogeneous septal enhancement in the arterial phase and persistent enhancement in the portal phase. The tumor was diagnosed as a benign neurogenic tumor or a retroperitoneal cavernous hemangioma at the time, and the patient was intended to be followed up at the outpatient clinic. However, it gradually increased to a maximum diameter of 35 mm over 4 years. Finally, it was completely resected by open laparotomy and pathologically diagnosed as AH. Retroperitoneal hemangioma is extremely rare in adulthood and has been confirmed in only 1-3% of all retroperitoneal tumors. To the best of our knowledge, only 6 cases of para-aortic AH have been reported. The incidence of this variant is very low. However, AH may be included in the differential diagnosis when a slowly progressing heterogeneous mass appears in the para-aortic region that exhibits a CT-enhanced pattern similar to a typical cavernous hemangioma.

Case report: biotin-thiamine-responsive basal ganglia disease with severe subdural hematoma on magnetic resonance imaging

Background: Biotin-thiamine-responsive basal ganglia disease (BTBGD) is a rare, treatable autosomal recessive neurometabolic disorder. This condition eventually leads to severe disability and death if not treated correctly. The clinical features of BTBGD, especially those with unusual complications, are not widely known by neurologists or pediatricians.Case presentation: A 4-month-old male infant was admitted to the hospital with a history of cough for the past 7 days and convulsions of 6 h duration. Physical examination showed confusion, bilateral pupillary light reflex delays, hypertonia of limbs, and brisk tendon reflexes of the limbs. Brain magnetic resonance imaging (MRI) showed multiple abnormal signals in the bilateral basal ganglia, lobes, corpus callosum, brainstem, and brain atrophy. However, his condition continued to worsen. Computed tomography performed 3 months later showed severe subdural hematoma and effusion. Subsequently, he underwent puncture drainage; however, his condition did not improve postoperatively. Repeated MRIs showed increasing subdural hematoma and effusion, and brain atrophy. The patient was diagnosed with BTBGD following whole-genome sequencing, which identified a novel compound heterozygous mutation of SLC19A3 gene. He was treated with biotin and thiamine, and the symptoms gradually improved. Subsequent MRIs showed a decrease in the subdural hematoma and effusion and partial improvement in brain atrophy.Conclusion: To the best of our knowledge, this is the first reported case of BTBGD, complicated by severe subdural hematoma. These observations extend our understanding of the clinical features, neuroimaging spectrum, and gene mutation spectrum of BTBGD. The phenotypic spectrum and pathophysiology of BTBGD are not completely understood and need to be studied further.

New device, 'old' allergens. Allergic contact dermatitis caused by the Dexcom G7 glucose sensor

BACKGROUND

Allergic contact dermatitis (ACD) has been reported as an adverse effect from the use of several glucose sensors and insulin pumps from different manufacturers. Isobornyl acrylate (IBOA) has been identified as a major culprit sensitizer, but also other acrylates and (modified) colophonium have been reported as causes of ACD.

OBJECTIVES

To report the two first cases diagnosed with ACD caused by the Dexcom G7 (DG7) glucose sensor.

PATIENTS AND METHODS

Two children with suspected ACD from DG7 were patch tested with our medical device series with an addition of selected test preparations including two variants of modified colophonium - methyl hydrogenated rosinate (MHR) and glyceryl hydrogenated rosinate (GHR). Both patients were also tested with acetone extracts made from different parts of the DG7 sensor. The extracts were analysed by gas chromatography-mass spectrometry (GC-MS).

RESULTS

Both patients tested positive to IBOA, hydroabietyl alcohol and GHR. In addition, patient 1 had a positive reaction to MHR and patient 2 had a positive reaction to colophonium. The GC-MS analyses showed the presence of IBOA and colophonium-related substances in the DG7 extracts.

CONCLUSIONS

Both patients were diagnosed with contact allergy to well-known medical device-related sensitizers. The presence of IBOA and (modified) colophonium in a newly introduced (on the Swedish market in 2023) glucose sensor is remarkable and indicates an inadequate toxicological assessment of the materials used in the sensor.

Tubal superfetation following frozen-thawed single-embryo transfers in two separate cycles: Case report and literature review

Superfetation is a very rare occurrence. In the context of assisted reproduction, it has been reported only as an intrauterine pregnancy after ovarian stimulation and/or embryo transfer in the presence of an undiagnosed ectopic pregnancy. Here we report a case of a 27-year-old anovulatory patient, gravida 1 para 1, who underwent two frozen-thawed single-blastocyst transfers in separate cycles. The patient reported that 12 days after the first transfer, she had menstrual bleeding and stopped her estradiol and progesterone supplementation without undergoing a blood human chorionic gonadotropin (βhCG) test. At her request, a second cycle was immediately initiated, with endometrial thickness measuring 4 mm. Eleven days after the second transfer, the βhCG value was inappropriately high. A right tubal pregnancy corresponding to 8 gestational weeks was diagnosed. Laparoscopy revealed a prominent right tubal pregnancy in addition to a significantly smaller left tubal pregnancy. The discordant tubal pregnancies were confirmed histologically. To our knowledge, superfetation involving a second ectopic pregnancy coexistent with a first, contralateral ectopic pregnancy consequent to consecutive in vitro fertilization procedures has not previously been described in the medical literature. This case emphasizes the importance of routine βhCG testing after every IVF cycle, even if apparently unsuccessful.

A Rare Prolactin-secreting Pituitary Carcinoma With Epidural and Thecal Metastases

Pituitary carcinomas are rare but associated with significant morbidity and mortality. They remain challenging to diagnose and manage. In this case, we describe a 56-year-old man who presented with erectile dysfunction and binocular vertical diplopia. He had central hypogonadism, secondary adrenal insufficiency, and central hypothyroidism on biochemical testing. His serum prolactin was 1517 mcg/L (1517 ng/mL; reference range 4-15 mcg/L), and his sellar magnetic resonance imaging showed a 2.0 × 2.2 × 3.1 cm pituitary tumor. Pathology revealed a prolactin-secreting carcinoma. Despite treatment with a high-dose dopaminergic, 2 transsphenoidal resections, and 1 course of radiation, prolactin levels continued to rise. He developed metastases to the epidural space and thecal sac from the thoracic to sacral spine, for which he received 12 cycles of temozolomide chemotherapy with initial clinical and biochemical response. This was followed by disease escape and progression. We discuss the clinical and imaging features that warrant a high index of suspicion for pituitary carcinoma and review contemporary treatment.

The possible clinical utility of the alcohol biomarker phosphatidylethanol for managing suspected alcohol withdrawal in hospitalized patients: A case report

BACKGROUND AND OBJECTIVES

The decision to initiate pharmacotherapy for alcohol withdrawal is typically based on examining self-reported use of alcohol and symptoms of withdrawal. Phosphatidylethanol (PEth) is a biomarker that could aim in clinical decision-making in withdrawal management.

METHODS

This report describes three cases highlighting the potential clinical utility of PEth in caring for individuals at risk for alcohol withdrawal.

RESULTS

Two of the cases received phenobarbital when their PEth showed that the risk of withdrawal was low and one case where PEth could have shown this was needed. The results were only available in a delayed fashion, however, could have been useful in informing clinical care.

DISCUSSION AND CONCLUSION

PEth can be a useful tool if available without delay. PEth can be used to quickly rule out alcohol withdrawal and avoid misdiagnoses and prolonged hospital stays.

SCIENTIFIC SIGNIFICANCE

This is a clinical case study available looking at PEth and withdrawal in hospitalized patients. It proposes that PEth can be used as a way to quickly rule out alcohol withdrawal to avoid misdiagnoses and the possibility of a prolonged hospital stay.

Complete remission after a single bisphosphonate infusion in isolated bone Langerhans cell histiocytosis lesion: a case report and a narrative review of the literature

Langerhans cell histiocytosis (LCH) is a rare disease with limited treatment options. We present a case involving a 57-year-old woman afflicted with an isolated LCH bone osteolytic lesion. A single bisphosphonate infusion significantly alleviated pain, and follow-up scans via CT, PET-CT, and MRI revealed a substantial recalcification of the lesion. Conducting an extensive literature review, we identified 46 cases documenting the efficacy of bisphosphonates in the context of LCH. These findings have raised interest in bisphosphonate infusion as a simple therapeutic alternative in similar situations, with benefits in terms of bone recalcification and pain control for individuals with LCH.

Peripheral Ulcerative Keratopathy following Systemic Treatment with Bortezomib: A Case Report

A 60-year-old patient was diagnosed with multiple myeloma in November 2020, and started treatment in December 2020 with bortezomib, dexamethasone, and thalidomide. Four months later, he presented to the ophthalmology emergency department with inflammation and pain in the left eye. Examination of the anterior segment revealed severe, mixed anterior squamous blepharitis with significant bilateral palpebral inflammation, dysfunction of the meibomian glands, and several styes on both eyelids bilaterally. A peripheral ulcerative keratopathy was detected while examining the left eye cornea, with an inferior infiltrate and significant thinning, approximately 5 mm in length, at the limbal margin (Figure 1). Tear break-up time was shortened bilaterally. In addition to palpebral hygiene and oral treatment with doxycycline 100 mg every 24 hours, the patient was prescribed the following topical treatment without preservatives: artificial tears with lipid emulsion, netilmicin 0,3% 0,4 ml eye drops every 6 hours and dexamethasone 1 mg/ml every 8 hours.

Extraoral type of intraductal papilloma in sublingual gland: A case report

INTRODUCTION

It is rare for intraductal papilloma (IDP), a benign papillary tumor, to occur in the sublingual gland (SLG).

CASE SUMMARY

A 55-year-old man incidentally found a painless mass in his left submandibular region (SMR). He had a history of two surgeries for bilateral SLG cyst. Contrast enhanced ultrasound (CEUS) and magnetic resonance imaging (MRI) were performed. The patient received trans-cervical excision of left residual SLG in combination with excision of left submandibular gland (SMG). The postoperative course was uneventful and no signs of recurrence during 5 months of follow-up.

DISCUSSION

For a SMR mass, extraoral type of IDP in SLG should be considered in the differential diagnosis.

Enhancing oral function: A case report on mandibular overdenture utilization with custom-made subperiosteal implant

Subperiosteal implants, previously set aside because of complications, are now emerging again as effective treatments for severe mandibular atrophy, aided by recent improvements in digital dentistry. Traditional dentures in such cases often face challenges with support and retention, necessitating complex regenerative procedures. This paper presents a case report of a 54-year-old male patient with significant mandibular atrophy who received a custom-made subperiosteal implant, showcasing promising results. The implant was precisely designed utilizing computed tomography (CT) scans, a 3D-printed model, the selective laser melting (SLM) technique, and constructed with biocompatible Ti6Al4V material. This innovative approach offered a practical solution, resulting in high patient satisfaction and no complications over a year of use.

A case of disseminated nocardiosis with orbital apex involvement and endophthalmitis

Nocardia is a rare cause of ocular infections and most commonly occurs secondary to trauma. Systemic Nocardiosis may have ocular involvement in rare cases. We report a case of disseminated nocardiosis with orbital apex involvement and endophthalmitis in an immunocompromised patient. The patient presented with respiratory sepsis, and later developed complete ptosis and ophthalmoplegia in the left eye. This was on the background of treatment with high-dose prednisolone. Magnetic resonance imaging showed enhancement of the entire clivus, extending into the left orbital apex and cavernous sinus. The patient was initially treated empirically for CNS tuberculosis. Bronchoscopic cultures returned positive for Nocardia farcinica, and the patient was treated with trimethoprim/sulfamethoxazole and weaned off previous corticosteroids.

The paraneurium and the tumefactive appearance of peripheral nerve neurolymphomatosis: illustrative case

BACKGROUND

Peripheral neurolymphomatosis (NL) is an often-misdiagnosed condition characterized by lymphomatous infiltration within the peripheral nerves. Its rarity and complexity frequently result in delayed diagnosis and suboptimal patient outcomes. This study aims to elucidate the role of the paraneurium (circumneurium) in NL, emphasizing its diagnostic and therapeutic significance.

OBSERVATIONS

A 72-year-old man presented with lesions on his right lower eyelid. Initial diagnostics were inconclusive until an excisional biopsy confirmed extranodal marginal zone lymphoma. Following a complete metabolic response to rituximab treatment, the patient relapsed 14 months later with progressive lymphoma and bilateral sciatic nerve involvement, as confirmed by positron emission tomography-computed tomography and magnetic resonance imaging.

LESSONS

This paper underscores the critical role of the paraneurium in NL, enhancing understanding of its pathophysiology. Integrating advanced imaging techniques have proved essential in accurately identifying neurolymphomatous involvement within the paraneurium. This study paves the way for more effective management strategies in NL and similar conditions, focusing on improving patient care and outcomes.

Severe Venous Calcifications in Phlebosclerotic Colitis and Significantly Decreased Expression in Betaine

Phlebosclerotic colitis (PC) is a rare type of chronic ischemic colitis. Its etiology is still unknown, and PC is also known as idiopathic mesenteric phlebosclerosis colitis. Currently, many studies have reported that long-term use of Chinese herbal medicine and drinking history are related to its pathogenesis. In the early stage of the lesion, due to insufficient understanding of PC, it is difficult to distinguish it from inflammatory bowel disease and other nonneoplastic intestinal diseases. We reported a case of severe diffuse total colon calcification with multiple misdiagnosis, summarizing and analyzing the clinical pathological characteristics to increase clinical and pathological physicians' understanding of the disease and reduce misdiagnosis. Moreover, for the first time, we conducted metabolomics sequencing on fresh intestinal specimens of PC, in order to explore the possible mechanism of severe calcification in the patient. We found that betaine was significantly decreased in the intestinal specimens of the patient, which is an amino acid that has been shown to improve vascular risk factors, and may be one of the mechanisms underlying severe calcification in the patient.

Regression of Endolymphatic Hydrops in Patient With Meniere's Disease Treated With Vestibular Neurectomy: A Case Report

Vestibular neurectomy is an effective method eliminating vertigo attacks in patients suffering from disabling Meniere's disease with no clinical improvement despite conservative and intratympanic therapy. Magnetic resonance imaging allows in vivo evaluation of changes manifesting in the inner ear after treatment; however, downgrading of the endolymphatic hydrops after vestibular neurectomy had not been previously described in the literature. In the present article, a case of a patient with unilateral severe Meniere's disease treated with selective vestibular nerve section from middle fossa approach was described. Clinical symptoms and audiovestibular tests were evaluated before and 13 months after the surgery. Complete resolution of vertigo episodes and hearing preservation was achieved. Magnetic resonance imaging was performed before and after the surgery using a 3 Tesla scanner with dedicated protocol after intravenous administration of gadolinium contrast agent. In the follow-up examination, regression of the cochlear and vestibular endolymphatic hydrops was visualized, which may suggest processes occurring in the labyrinth as a result of the vestibular efferent fibers section.

Anaplerotic Therapy Using Triheptanoin in Two Brothers Suffering from Aconitase 2 Deficiency

Citric acid cycle deficiencies are extremely rare due to their central role in energy metabolism. The ACO2 gene encodes the mitochondrial isoform of aconitase (aconitase 2), the second enzyme of the citric acid cycle. Approximately 100 patients with aconitase 2 deficiency have been reported with a variety of symptoms, including intellectual disability, hypotonia, optic nerve atrophy, cortical atrophy, cerebellar atrophy, and seizures. In this study, a homozygous deletion in the ACO2 gene in two brothers with reduced aconitase 2 activity in fibroblasts has been described with symptoms including truncal hypotonia, optic atrophy, hyperopia, astigmatism, and cerebellar atrophy. In an in vivo trial, triheptanoin was used to bypass the defective aconitase 2 and fill up the citric acid cycle. Motor abilities in both patients improved.

Giant retinal pigment epithelial tear following photodynamic therapy for the bullous variant of central serous chorioretinopathy: A case report

RATIONALE

The bullous variant of central serous chorioretinopathy (CSC) is a severe form of chronic CSC. Patients with the bullous variant of CSC have an increased risk of experiencing multiple pigment epithelial detachments (PEDs) and retinal pigment epithelium (RPE) tears. Photodynamic therapy (PDT) is a treatment for the bullous variant of CSC. RPE tear is a possible postoperative complication of PDT for eyes with PEDs. To our knowledge, no cases of giant RPE tears following PDT for the bullous variant of CSC have been reported previously. This case report presents the first instance of a giant RPE tear after half-time PDT for the bullous variant of CSC, accompanied by a series of images depicting the tear development.

PATIENT CONCERNS

A 63-year-old male patient presented with rapidly deteriorating vision in his left eye over a 3-month period. He also reported a previous episode of vision loss in his right eye 2 years prior. Best-corrected visual acuity (BCVA) in the left eye was 0.2.

DIAGNOSIS

The right eye was diagnosed with chronic non-bullous CSC, while the left eye was diagnosed with the bullous variant of CSC with a large PED.

INTERVENTIONS

Half-time PDT was administered to the left eye.

OUTCOMES

One month after half-time PDT, a giant RPE tear exceeding 3 clock-hours in size was confirmed in the lower temporal quadrant of the left eye. Three months after the initial half-time PDT, a second half-time PDT was performed owing to recurrent retinal detachment. Two months after the second half-time PDT, the retinal detachment resolved, and BCVA improved to 0.4, 6 months after the second half-time PDT.

LESSONS

In cases where the bullous variant of CSC is complicated by extensive PED, clinicians should consider the potential development of a giant RPE tear as a treatment complication.

Severe fibromyalgia alleviated by the unique muscle relaxation method of applying low force: A case report

RATIONALE

Fibromyalgia (FM) is characterized by idiopathic persistent chronic pain in the ligaments or musculoskeletal system, and more than half of the patients with FM might have migraine headaches. Direct musculoskeletal intervention could be a non-pharmacological management to relieve symptoms. However, patients with severe FM often have intense pain from only a soft touch, thereby rendering musculoskeletal intervention challenging.

PATIENT CONCERNS

A 47-year-old man had progressing intense pain, and this affected his everyday life. There were no abnormal physical findings on laboratory examination such as levels of complement, antinuclear antibodies, and C-reactive protein, which were within normal limits. Magnetic resonance imaging did not indicate abnormalities.

DIAGNOSES, INTERVENTIONS, AND OUTCOMES

The patient satisfied the American College of Rheumatology criteria. Finally, we made a final diagnosis of fibromyalgia. The therapeutic intervention of Kanshoho, the unique muscle relaxation technique with low force, relieved his pain.

LESSONS

If Kanshoho is carefully applied in a state of hospitalization under surveillance by an experienced physician, it could be a promising muscle relaxation method. Relaxing the trapezius muscle and reducing its intramuscular pressure might be key in treating patients with severe FM. However, it needs elucidation of its mechanism.

Diagnosis and rescue of malignant hyperthermia induced by anesthesia during radical surgery in a cervical cancer patient using the National Remote Emergency System: A case report

RATIONALE

Malignant hyperthermia (MH) is a rare yet serious medical complication that typically arises following general anesthesia or the administration of specific anesthetics. Due to the infrequency of MH, anesthesiologists often lack sufficient expertise in identifying and managing it, leading to misdiagnosis and inappropriate treatment. There is an urgent need to enhance the diagnosis and management of MH through the utilization of relevant tools.

PATIENT CONCERNS

In this case, a 52-year-old woman underwent radical cervical cancer surgery under general anesthesia, with no family or significant medical history. She experienced a gradual increase in end-tidal carbon dioxide (ETCO2) to a maximum of 75 mm Hg and a rise in body temperature from 36.5 to 37.5 °C in a very short period, as well as a blood gas analysis showing a pH of 7.217.

DIAGNOSIS

The anesthesiologist immediately used The WeChat applet-based National Remote Emergency System for Malignant Hyperthermia (MH-NRES), and the score was 40, which indicated that the patient was very likely to have MH.

INTERVENTIONS

We immediately discontinued sevoflurane and switched total intravenous anesthesia to maintain general anesthesia, with a rapid intravenous infusion of dantrolene sodium.

OUTCOMES

The ETCO2 and the temperature quickly dropped to normal, followed by successful completion of the surgery, and the patient was discharged 8 days after surgery.

LESSONS

The experience can provide a basis use of MH-NRES and improve the ability of anesthesiologists to deal with intraoperative MH as well as increase the survival probability of patients.

Metacarpophalangeal joint reconstruction using a costal osteochondral graft: A case report

RATIONALE

The conventional treatment of giant cell tumors is intralesional curettage with local adjuvant therapy. Because hand tumors have a high local recurrence, the primary goal for treating tumors of the hand is to eradicate the lesion.

PATIENT CONCERNS

To preserve the metacarpophalangeal (MCP) joint function as well as avoid further recurrence after surgery.

DIAGNOSES

The giant cell tumor invades the patient's MCP joint in an index proximal phalanx.

INTERVENTIONS

Using computer-aided design and three-dimensional printing techniques, we reformed the original shapes of the MCP joint and its peripheral bone to replica models. The surgeon then performed an en bloc resection and proximal phalanx with MCP joint reconstruction by fabricating the patient's costal osteochondral graft during the operation.

OUTCOMES

After 6 months of rehabilitation, the patient's finger functions could pinch and grasp objects naturally. At the 1-year follow-up, the range of motion of the MCP, proximal interphalangeal, and distal interphalangeal joints improved from flexion of 35° to 60°, 75° to 85°, and 60° to 80°, respectively. The hand function achieved the mean performance of non-preferred hands for young females at the postoperative 3-year follow-up.

LESSONS

The customized prototyping technique has the potential to replica the original patient's bony graft to reach the goal of minimizing the defects at the donor site and maximizing the function of the reconstructed MCP joint.

Breast mucosa-associated lymphoid tissue lymphoma: A case report and literature review

BACKGROUND

Mucosa-associated lymphoid tissue (MALT) lymphoma, also known as extranodal marginal zone lymphoma, is more commonly detected in the stomach and rarely in the breast. Our study presented a clinical and pathological examination of a patient diagnosed with breast MALT lymphoma, supplemented with pertinent research, to offer guidance for the diagnosis and treatment of this condition.

PEOPLE CONCERNS

The occurrence of breast MALT lymphoma has risen in the past decade, but its etiology, progression and treatment response are less well-studied.

DIAGNOSIS

Breast MALT lymphoma was diagnosed by excisional biopsy and histopathology.

INTERVENTIONS

Following breast MALT lymphoma diagnosis, the patient was transferred to the hematology department for further treatment, and she made the decision to continue observing.

OUTCOMES

After 3 months of observation, the patient remained asymptomatic.

CONCLUSION

Breast MALT lymphoma is an indolent disease with an asymptomatic presentation, There are no standardized treatment guidelines for breast MALT lymphoma, treatment must be tailored to the patient willingness to treat and the severity of the disease. Hence, in order to give patients a better chance of cure, more research is needed to explore its pathogenesis and more clinical trials are needed investigate the treatment of this disease.

Early intrauterine pregnancy with an intrauterine device in place and terminated with spontaneous abortion: A case report

RATIONALE

The overall pregnancy rate in individuals with an intrauterine device (IUD) for contraception is <1%. If pregnancy occurs while an IUD is in place, there is a higher risk of an ectopic pregnancy. We report the case of a woman with an IUD who was 7 weeks pregnant and experienced a spontaneous abortion 1 week later.

PATIENT CONCERN

A 32-year-old woman presented to our outpatient department with intermittent vaginal staining for several days.

DIAGNOSES

She was 7 weeks pregnant and had an IUD in place for over 4 years. A vaginal examination revealed no vaginal bleeding and no blood clots; however, a parous cervix was observed. The IUD string was not visible. Transvaginal ultrasonography revealed a gestational sac in the uterine cavity, with a fetal pole and a crown-rump length of 11.4 mm. The fetal heart rate was 159 beats/min. The IUD was located in the retroplacental region. The bilateral adnexa appeared normal (right ovary, 2.9 cm; left ovary, 2.5 cm). The patient was diagnosed with an intrauterine pregnancy with an IUD in place and threatened abortion.

INTERVENTIONS

Attempts to remove the IUD were abandoned due to its location, and conservative treatment was initiated with Utrogestan (100 mg) administered 3 times a day for 1 week. Bed rest was advised.

OUTCOMES

Unfortunately, she experienced a complete abortion 1 week later.

LESSONS

The novelty of this case report lies in the rare occurrence of an intrauterine pregnancy with a long-term IUD in place, the challenges posed by the IUD's specific location, and the complex management of threatened abortion in this context. Our case highlights the diagnostic management approach for intrauterine pregnancy with an IUD in place. Furthermore, it explores the impact of IUD location on pregnancy prognosis.

Management of six episodes of intraoperative cardiac arrests in an infant with traumatic bronchial rupture: A case report

RATIONALE

Traumatic bronchial rupture in infants usually necessitates surgical intervention, with few reports documenting instances of multiple cardiac arrests occurring during surgery under conditions of severe hypoxemia.

PATIENT CONCERNS

A 3-year-old boy after trauma presented with severe hypoxemia for 2 days and was urgently transferred to the operating room for surgery, 6 episodes of cardiac arrest happend during surgery.

DIAGNOSES

The baby was diagnosed with bronchial rupture based on the history of trauma, clinica manifestations, and intraoperative findings.

INTERVENTIONS

Intrathoracic cardiac compression and intravenous adrenaline were administrated.

OUTCOMES

The normal sinus rhythm of the heart was successfully restored within 1 minute on each occasion, facilitating the smooth completion of the surgical procedure. By the end of surgery, SpO2 levels had rebounded to 95% and remained stable.

LESSONS

Inadequate management of bronchial ruptures in infants frequently coincides with severe hypoxemia, necessitating immediate surgical intervention. Prompt identification and management of cardiac arrest by anesthetists during surgery is imperative to reduce mortality.

A novel ABCD1 gene mutation causes adrenomyeloneuropathy presenting with spastic paraplegia: A case report

RATIONALE

X-linked adrenoleukodystrophy (X-ALD) is caused by mutations in the ABCD1 gene leading to very long chain fatty acid (VLCFA) accumulation. The disease demonstrates a spectrum of phenotypes including adrenomyeloneuropathy (AMN). We aimed to identify the genetic basis of disease in a patient presenting with AMN features in order to confirm the diagnosis, expand genetic knowledge of ABCD1 mutations, and elucidate potential genotype-phenotype associations to inform management.

PATIENT CONCERNS

A 29-year-old male presented with a 4-year history of progressive spastic paraplegia, weakness of lower limbs, fecal incontinence, sexual dysfunction, hyperreflexia, and positive Babinski and Chaddock signs.

DIAGNOSES

Neuroimaging revealed brain white matter changes and spinal cord thinning. Significantly elevated levels of hexacosanoic acid (C26:0) and tetracosanoic acid (C24:0) suggested very long chain fatty acids (VLCFA) metabolism disruption. Genetic testing identified a novel hemizygous ABCD1 mutation c.249dupC (p.F83fs). These findings confirmed a diagnosis of X-linked ALD with an AMN phenotype.

INTERVENTIONS

The patient received dietary counseling to limit VLCFA intake. Monitoring for adrenal insufficiency and consideration of Lorenzo's oil were advised. Genetic counseling and testing were offered to at-risk relatives.

OUTCOMES

At present, the patient continues to experience progressive paraplegia. Adrenal function remains normal thus far without steroid replacement. Family members have undergone predictive testing.

LESSONS

This case expands the known mutation spectrum of ABCD1-linked X-ALD, providing insight into potential genotype-phenotype correlations. A thoughtful diagnostic approach integrating clinical, biochemical and genetic data facilitated diagnosis. Findings enabled genetic counseling for at-risk relatives regarding this X-linked disorder.

Acupuncture therapy for isolated ischemic oculomotor nerve palsy: A case report

BACKGROUND

Isolated ischemic oculomotor nerve palsy as a type of ophthalmic disease is rarely observed in clinical practice. Quality of life is frequently impacted by isolated ischemic oculomotor nerve palsy due to its lack of treatment options and long-term visual impairment. We describe an acupuncture-treated instance of isolated ischemic oculomotor paralysis.

METHODS

Acupoints including Jingming (BL 1), Chengqi (ST 1), Cuanzhu (BL 2), and Sizhukong (TE 23) on the right side, and bilateral Fengchi (GB 20), Waiguan (TE 5), Hegu (LI 4), and Zulinqi (GB 41) were selected for needling. Each treatment lasted for 30 minutes, once every other day. Acupuncture treatment was administered for a total of 11 times.

RESULTS

Acupuncture is a promising treatment option for isolated ischemic oculomotor nerve palsy.

CONCLUSIONS

Ischemic oculomotor nerve paralysis can affect the quality of life of patients. Acupuncture intervention can promote the recovery of the disease is a very effective treatment measure.

Successful treatment of gastric cancer 10 years after heart transplantation: A case report

BACKGROUND

While survival rates among cardiac allograft recipients have improved, there has been a rise in post-transplant malignancies, with gastric cancer being less commonly reported. This study presented a successful treatment of gastric cancer in an individual 10 years after undergoing a heart transplant.

CASE PRESENTATION

A 66-year-old Chinese man presented to the gastrointestinal clinic with a complaint of diagnosis of gastric cancer for 4 months and treated with neoadjuvant therapy for 1 month. He has undergone orthotopic heart transplantation 10 years earlier due to a myocardial infarction. Physical examination and laboratory tests did not reveal any significant abnormalities. Abdominal contrast-enhanced computed tomography (CT) imaging indicated a gastric mass near the greater curvature, with gastroscopy suggesting a carcinoma at the esophagogastric junction, Siewert III. An echocardiogram indicated left atrial enlargement with mild mitral and tricuspid regurgitation. The diagnosis suggested that his gastric cancer at the esophagogastric junction was a consequence of long-term immunosuppressive therapy. A multidisciplinary team (MDT) consultation recommended a proximal radical gastrectomy. Postoperatively, the patient received 4 cycles of adjuvant chemotherapy with XELOX combined with Herceptin, initiated a month after surgery. During the 1-year follow-up, the patient showed commendable recovery, with no signs of tumor recurrence or metastasis.

CONCLUSION

This case underscores the potential risk of malignancy from immunosuppressive agents in transplant recipients. The successful management of this complex scenario underscores the indispensable role of an MDT approach in treating such unique and challenging cases.

Successful treatment of severe primary mitral regurgitation due to rheumatic aetiology using a novel-designed transcatheter edge-to-edge repair system

The transcatheter edge-to-edge mitral valve repair (TEER) has been recommended as a reliable treatment option for selected patients with severe degenerative and functional mitral regurgitation (MR). Although MR patients with rheumatic etiology were excluded from two significant trials (EVEREST II and COAPT) that established a role for the TEER in degenerative and functional MR. However, it has been reported that the TEER procedure could be safely and effectively performed in carefully selected rheumatic MR patients. Therefore, we share a case report of successfully treating severe rheumatic MR using a novel-designed TEER system (JensClipTM).

Over-the-scope clip as a rescue treatment for massive bleeding due to Dieulafoy lesion at the colorectal anastomosis: A case report

RATIONALE

The bleeding of Dieulafoy lesion predominantly involves the proximal stomach and leads to severe gastrointestinal bleeding. However, these lesions have also been reported in the whole gastrointestinal tract. Bleeding of Dieulafoy lesions at the anastomosis was seldomly reported and was very easy to be ignored clinically.

PATIENT CONCERNS

We describe a 72-year-old woman with a past history of surgery for rectal carcinoma hospitalized with chief complaint of massive rectal bleeding. No gross bleeding lesion was found during the first emergency colonoscopy. Despite multiple blood transfusions, her hemoglobin rapidly dropped to 5.8 g/dL.

DIAGNOSIS

She was diagnosed with Dieulafoy lesion at the colorectal anastomosis during the second emergency colonoscopy.

INTERVENTIONS

Primary hemostasis was achieved by endoscopic hemostatic clipping. However, she experienced another large volume hematochezia 3 days later, and then received another endoscopic hemostatic clipping. She was improved and discharged. However, this patient underwent hematochezia again 1 month later. Bleeding was arrested successfully after the over-the-scope clip (OTSC) was placed during the fourth emergency colonoscopy.

OUTCOMES

This patient underwent 4 endoscopic examinations and treatments during 2 hospitalizations. The lesion was overlooked during the first emergency colonoscopy. The second and third endoscopes revealed Dieulafoy lesion at the colorectal anastomosis and performed endoscopic hemostatic clippings, but delayed rebleeding occurred. The bleeding was stopped after the fourth emergency colonoscopy using OTSC. There was no further rebleeding during hospitalization and after 2-year of follow-up.

LESSONS

As far as we know, there is no reported case of lower gastrointestinal bleeding caused by Dieulafoy lesion at the colorectal anastomosis, OTSC is a safe and effective rescue treatment for Dieulafoy lesions.

Navigating uncharted territory: a case report and literature review on the remarkable response to personalized crizotinib containing combinational therapy in a pazopanib refractory patient with novel alterations

This paper presents a patient with a novel Ig-like-III domain fibroblast growth factor receptor (FGFR2) alteration (W290_P307>C) along with CDKN2A/B alterations and a cadherin 1 (CDH1) alteration. Initial responsiveness to pazopanib monotherapy was encouraging, yet progression occurred after 7.5 months. Following progression, the molecular tumor board recommended a combination therapy approach comprising pazopanib, crizotinib, and palbociclib to target all of the changed pathways at the same time. Pazopanib was chosen to specifically target the FGFR2 alteration, while crizotinib was selected due to its potential synthetic lethality with the CDH1 alteration. In addition, the CDK4/6 inhibitor palbociclib was administered to address the CDKN2A/B alterations. The patient exhibited a remarkable and sustained response to this innovative combination. This case not only underscores the potential of tyrosine kinase inhibitors, exemplified by pazopanib, as a viable alternative for patients without access to pan-FGFR inhibitors, but it also emphasizes their efficacy beyond commonly detected point mutations and rearrangements. Notably, the outstanding response to combination therapy, including crizotinib, in a patient with a CDH1 alteration, further substantiates the preclinical evidence of synthetic lethality between crizotinib and CDH1 alterations. To our knowledge, this represents the first clinical evidence demonstrating the efficacy of crizotinib in a patient with a CDH1 alteration. Through careful dosage adjustments and consideration of individualized genomic information, this case exemplifies the power of personalized medicine in achieving favorable treatment outcomes.

Multimodal ultrasound diagnosis of epididymo-orchitis with secondary testicular infarction: A case report

We report a case of a 48-year-old man with testicular infarction caused by epididymo-orchitis (EO). Multimodal ultrasound showed extensive necrosis of the testis, and the patient underwent right orchiectomy. Postoperative pathology confirmed extensive necrosis of the testis. After 3 months of follow-up, the examination of scrotal ultrasound showed that the left testis and epididymis had no obvious abnormality.

Personalized treatment with PARP inhibitors in advanced urothelial carcinoma: a case report and literature review

Bladder cancer (BC) poses a significant health challenge, particularly in metastatic cases, where the prognosis is unfavorable and therapeutic options are limited. Poly ADP-ribose polymerase (PARP) inhibitors have gained approval for use in various cancer types, but their application in BC remains controversial, despite the notable prevalence of DNA damage response alterations in advanced or metastatic urothelial carcinomas. In this report, we describe a 66-year-old heavy-smoking female diagnosed with muscle-invasive BC. She underwent multiple rounds of chemotherapy and radiation, yet her disease remained poorly controlled, leading to metastasis in the left obturator internus muscle. Comprehensive genomic profiling through FoundationOne® Liquid CDx, examining a 324-gene panel using circulating tumor DNA from blood samples, revealed a pathogenic ATM gene alteration (p.Q654fs*10, c.1960delC), suggesting potential eligibility for PARP inhibitor therapy. Remarkably, the patient achieved a complete response to talazoparib, prompting an optimal investigation into BC candidates for this promising therapy.

Arachnoid bands in hemifacial spasm: an overlooked etiology? Illustrative case

BACKGROUND

Primary hemifacial spasm (HFS) is usually caused by arterial compression of the facial nerve at the root exit zone at the brainstem. Rarely, a purely venous compression is seen. However, arachnoid bands strangulating the facial nerve have not been recognized as a cause of hemifacial spasm.

OBSERVATIONS

The authors present a case of a 24-year-old female who had experienced HFS for 9 years. Endoscopic inspection of the root exit zone revealed no vascular compression but an arachnoid band strangulating the facial nerve. After cutting the band, the lateral spread response disappeared, and the patient was immediately spasm free after the surgery. Two years later, she was still doing well without any spasms.

LESSONS

This is the third patient in the authors' series of 535 patients who had no vascular conflict but rather a strangulation of the nerve by arachnoid bands. All patients have remained spasm free. To the authors' knowledge, no other group has reported arachnoid bands as an etiological factor of HFS so far.

Primary Pulmonary Lymphoepithelioma-like Carcinoma: A Case Report Utilizing Camrelizumab and Anlotinib for Prolonged Survival

BACKGROUND

Primary Pulmonary Lymphoepithelioma-like Carcinoma (PPLELC) is a rare form of cancer for which no standard treatment has been established to date. Patients with advanced-stage PPLELC generally have a poor prognosis with overall survival of 22.7 months.

CASE PRESENTATION

Here, we report a case of advanced primary pulmonary lymphoepithelioma-like carcinoma. Initially, the patient underwent a first-line (GP) and a second-line (DP) of chemotherapy, which provided temporary relief but resulted in varying degrees of myelosuppression. When the disease progressed again, we administered a third-line treatment consisting of camrelizumab combined with anlotinib.

RESULT

This resulted in a progression-free survival of over 26 months without significant toxic side effects.

CONCLUSION

Our findings suggest that combining camrelizumab and anlotinib could lead to a long progressionfree survival in patients with advanced PPLELC.

a case report

OBJECTIVE

This paper presents a rare case of subacute bacterial endocarditis (SBE) following a herpes zoster (HZ) episode, with no prior records found in the existing literature.

PATIENT INFORMATION

Specifically, we describe a case of a 76-year-old female whose diagnosis of SBE was hindered by the concurrent manifestation of HZ symptoms, which had emerged 3 weeks before the onset of SBE indicators.

FOLLOW-UP AND OUTCOMES

This delay in diagnosis resulted in profound complications, including a cerebrovascular accident and significant mitral valve destruction.

DISCUSSION

HZ episodes have not conventionally been linked in the medical literature to the occurrence of SBE. Nonetheless, it is noteworthy that HZ infections have been associated with the development of other consequential bacterial infections, such as pneumonia and necrotizing fasciitis.This case underscores the necessity for medical practitioners to recognize the possibility of HZ symptoms obscuring indications of critical underlying conditions and infections. The implications of this report highlight the significance of maintaining heightened vigilance for signs of other severe infections when managing patients presenting with HZ symptoms.

Phantom limb pain, traumatic neuroma, or nerve sheath tumor? Illustrative case

BACKGROUND

Phantom limb pain and traumatic neuromas are not commonly seen in neurosurgical practice. These conditions can present with similar symptoms; however, management of traumatic neuroma is often surgical, whereas phantom limb pain is treated with conservative measures.

OBSERVATIONS

A 77-year-old female patient with a long-standing history of an above-the-knee amputation experienced severe pain in her right posterior buttocks area for several years' duration, attributed to phantom limb pain, which radiated down the stump of her leg and was treated with a variety of conservative measures. A recent exacerbation of her pain led to a prolonged hospitalization with magnetic resonance imaging of her leg stump, revealing a mass in the sciatic notch, at a relative distance from the stump. The anatomical location of the mass on the sciatic nerve in the notch led to a presumed radiological diagnosis of nerve sheath tumor, for which she underwent excision. At surgery, a neuroma of the proximal portion of the transected sciatic nerve that had retracted from the amputated stump to the notch was diagnosed.

LESSONS

Traumatic neuromas of transected major nerves after limb amputation should be considered in the differential diagnosis of phantom limb pain.

Case report

BACKGROUND

Congenital syphilis is a vertical infection caused by Treponema pallidum. Despite the implementation of preventive strategies during pregnancy, its incidence is increasing, and it constitutes an important public health problem. Most patients with congenital syphilis are asymptomatic; however, a small group may develop severe disease at birth with the need of advanced resuscitation in the delivery room, acute hypoxemic respiratory failure, and hemodynamic instability. Therefore, awareness is needed.

METHODS AND RESULTS

This series describes the clinical course of two late preterm infants with congenital syphilis who developed acute hypoxemic respiratory failure, pulmonary hypertension, and circulatory collapse early after birth. Integrated hemodynamic evaluation with neonatologist-performed echocardiography (NPE) and therapeutic management is provided.

CONCLUSIONS

A comprehensive hemodynamic evaluation including early and serial functional echocardiography in these patients is needed to address the underlying complex pathophysiology and to help to establish accurate treatment.

Clinical and genetic analysis of a case of Gitelman syndrome accompanied with Graves disease and adrenocortical adenoma: A case report

RATIONALE

Gitelman syndrome (GS), also known as familial hypokalemia and hypomagnesemia, is a rare autosomal recessive inherited disease caused by primary renal desalinization caused by impaired reabsorption of sodium and chloride ions in the distal renal tubules. We report a case of clinical and genetic characteristics of GS accompanied with Graves disease and adrenocorticotrophic hormone (ACTH)-independent adrenocortical adenoma.

PATIENT CONCERNS

The patient is a 45 year old female, was admitted to our hospital, due to a left adrenal gland occupying lesion as the chief complaint.

DIAGNOSIS

The patient was finally diagnosed as GS with Graves disease and adrenocortical adenoma.

INTERVENTIONS

Potassium magnesium aspartate (1788 mg/d, taken orally 3 times a day (supplement a few times a day, intake method, treatment duration). Contains 217.2 mg of potassium and 70.8 mg of magnesium, and potassium chloride (4.5 g/d, taken orally 3 times a day (supplement a few times a day, intake method, and treatment duration); Potassium 2356 mg), spironolactone (20 mg/d, taken orally once a day (supplement a few times a day, intake method, treatment duration). After 3 months of treatment, the patient's blood potassium fluctuated between 3.3-3.6 mmol/L, and blood magnesium fluctuated between 0.5-0.7 mmol/L, indicating a relief of fatigue symptoms.

OUTCOMES

On the day 6 of hospitalization, the symptoms of dizziness, limb fatigue, fatigue and pain were completely relieved on patient. In the follow-up of the following year, no recurrence of the condition was found.

LESSONS

The novel c.1444-10(IVS11)G > A variation may be a splicing mutation. The compound heterozygous mutations of the SLC12A3 gene may be the pathogenic cause of this GS pedigree.

Smokeless tobacco keratosis in oral mucosa with epithelial dysplasia: A case report

RATIONALE

Smokeless tobacco use is a risk factor for the development of various oral lesions, among which is smokeless tobacco keratosis (STK). This condition is caused by constant frictional irritation of smokeless tobacco products against the oral mucosa and appears as a White-to-gray plaque with wrinkling.

PATIENT CONCERNS

A 50-year-old man who had been using smokeless tobacco for 24 years visited our clinic complaining of changes in the lower right sulcus of the oral cavity for 10 days. Clinical examination revealed a unilateral, nonhomogeneous White lesion in the area of the complaint. Histopathological examination showed hyperkeratosis, areas of keratin plugging, and mild dysplastic epithelial changes.

DIAGNOSIS

The clinico-histopathological correlation suggested a diagnosis of STK with focal mild epithelial dysplasia.

INTERVENTION AND OUTCOME

A comprehensive management plan included maintaining oral hygiene, education on the detrimental effects of smokeless tobacco, advice to cease smoking, and regular follow-up to monitor the potential for malignant transformation. The patient was referred to a tobacco cessation society for tailored advice and counseling. On follow-up visits, there was an improvement in the lesion after habitual cessation.

LESSONS

The diagnosis of tobacco-related oral lesions is often delayed, which may result in malignant transformation. This illustrates the need to train healthcare professionals to identify tobacco-related conditions at an early stage and to educate patients regarding the harmful effects of tobacco use.

Serotonin syndrome treated with cyproheptadine using NPi from a digital pupillometer as a therapeutic indicator: A case report

RATIONALE

Serotonin syndrome is a potentially life-threatening condition resulting from the use of antidepressants, their interactions with other serotonergic medications, or poisoning. It presents with a triad of psychiatric, dysautonomic, and neurological symptoms and is sometimes fatal. While cyproheptadine is a specific treatment option, the optimal duration of its administration remains unclear. The purpose of this report is to quantitatively assess the endpoints of serotonin syndrome treatment. Based on the hypothesis that neurological pupil index (NPi) on a digital pupil recorder would correlate with the severity of the serotonin syndrome, we administered cyproheptadine using NPi as an indicator.

PATIENT CONCERNS

A patient with a history of depression was brought to our hospital after he overdosed on 251 tablets of serotonin and noradrenaline reuptake inhibitors.

DIAGNOSES

On day 3, the patient was diagnosed with serotonin syndrome.

INTERVENTIONS

Cyproheptadine syrup was administered at 4 mg every 4 hours. The NPi of the automated pupillometer was simultaneously measured. On day 5, the NPi exceeded 3.0 cyproheptadine was discontinued.

OUTCOMES

The patient was discharged on day 7.

LESSONS

The lack of considerable improvement during the treatment period suggests that the patient may have improved on his own. In this case, the relationship between NPi and the severity of serotonin syndrome could not be determined.

Bilateral sinonasal inverted papillomas originating from both sides of the frontal sinus and the left lamina papyracea: A case report

RATIONALE

The present investigation documented a case of bilateral sinonasal inverted papilloma (SNIP) that arose from both sides of the frontal sinus and ethmoid sinus. The occurrence of bilateral involvement of the nasal cavities and frontal sinus is rather infrequent.

PATIENT CONCERNS

Informed consent was obtained from the patient.

DIAGNOSIS

Bilateral SNIP.

INTERVENTIONS

The tumor was completely removed by Draf III endoscopic resection complemented by an external eyebrow arch approach, and the postoperative recovery was uneventful.

OUTCOMES

The purpose of this paper is to present a comprehensive reference for the management of bilateral SNIP that affects the frontal sinuses.

LESSONS

This study addresses the staging and surgical management of bilateral SNIP, along with a review of the factors contributing to its recurrence. The recommended treatment method involves applying the Draf III technique combined with an external nasal approach.
