A young male with coexisting astrocytoma and renal cell carcinoma

Familial cancer syndrome is a genetic condition that causes an individual to be at increased risk for specific types of cancers. There are different familial cancer syndromes, each of which is associated with a specific set of characteristic cancers. Atypical presentations such as the combination of two types of cancers involving the same primary site with a slightly different pathology are not uncommon. The reason for such a high degree of phenotypic variation could be due to somatic mosaicisms which, although rare, have been reported in association with some of the familial cancer syndromes. We report a case of a 44-year-old Caucasian male with coexisting astrocytoma and Renal Cell Carcinoma (RCC), in whom the diagnosis of Von Hippel-Lindau (VHL) syndrome was considered. Although the patient tested negative for the classic VHL gene, the possibility of somatic mosaicism could not be ruled out. This case reflects the importance of having a high index of suspicion to screen the patients with more than one type of malignancies for familial cancer syndrome, as it may present with atypical features and the diagnosis of familial cancer syndrome has important implications in genetic counseling.

Know Your Audience

Purpose: To identify the chief complaints and demographics at Clinica Esperanza, a student-run free clinic for an underserved Hispanic population. Methods: A retrospective chart review of patient files from 2005 through 2010 was undertaken, as approved by the University of Tennessee Health Science Center’s Institutional Review Board. Results: From 2005 through 2010, Clinica Esperanza fielded 2551 patient visits, consisting of 951 unique patients, 609 females and 342 males. Mean age was 34 years, and 60% of patients presented once, while 13% followed up for 1 year, 9% for 2 years, 6% for 3, 6% for 4, and 4% for 5. “Pap smear,” “abdominal pain,” and “follow-up lab results” ranked, in order, as the 3 top chief complaints. Discussion: Resulting data have led to several improvements. The clinic has remained open weekly to improve patient continuity. With the top 10 chief complaints identified, they are better addressed. More funding is allocated for speculums and proper training of Pap smear technique. Systematic reporting of lab results is being implemented. Physical therapists and pharmacists now participate to address musculoskeletal and medication-based needs, respectively. A volunteer gastroenterologist has been recruited to provide specialized care for abdominal pain. An electrocardiogram machine is now used to evaluate chest pain. To improve student-patient communication, online language learning modules have been created. Conclusions: Based on these data, improvements in health care services have been made, including better continuity, emphasis on top chief complaints, and provider education in medical Spanish. Future plans include on-site pharmacy, smoother referrals, and similar clinics on the University of Tennessee Health Science Center’s other campuses.

Cold-induced urticaria with a familial transmission: a case report and review of the literature

Introduction

Cryopyrin-associated periodic syndrome is a rare genetic disorder causing cold-induced urticaria, severe arthralgias, and (potentially) renal failure and hearing loss. Therapies that effectively control the symptoms and prevent the complications of this debilitating disorder are now available, making recognition of this disease important.

Case presentation

A 60-year-old Caucasian woman presented with complaints of rash and joint pains to a general medicine clinic. Her history showed that her symptoms were linked to cold exposure, but the results of a cold stimulation time test were negative. Several generations of her family had similar symptoms.

Conclusions

This case highlights the importance of considering cryopyrin-associated periodic syndrome in the differential diagnosis of cold-induced urticaria. Several medications targeting interleukin-1-beta are available, providing significant relief from symptoms and improvement in quality of life in affected patients.

Transient binocular visual loss: a rare presentation of ventriculoperitoneal shunt malfunction

The authors report the case of a 27-year-old male with ventriculoperitoneal shunt (VPS) for hydrocephalus presenting with episodic transient binocular visual loss (TBVL) and headache. Complete physical, bedside shunt examination and funduscopy were unremarkable. Laboratory investigation, shunt series and imaging studies failed to reveal any acute abnormalities. Interrogation of the shunt system identified a valve malfunction which was corrected with resultant symptomatic relief and the patient was discharged home in stable condition. VPS malfunction occurs secondary to infection or mechanical failure such as obstruction, tubing fracture, shunt migration and over drainage. Resultant raised intracranial pressure leads to symptoms of headache, nausea, vomiting and gait abnormalities. Visual defects including blindness has been occasionally reported from shunt malfunction. Rare complications include cerebrospinal fluid oedema, colonic perforation, paraparesis and parkinsonism. TBVL due to shunt malfunction remains an uncommon presentation and requires a high index of clinical suspicion while evaluating these patients.

Enhancing teamwork between chief residents and residency program directors: description and outcomes of an experiential workshop

BACKGROUND

An effective working relationship between chief residents and residency program directors is critical to a residency program's success. Despite the importance of this relationship, few studies have explored the characteristics of an effective program director-chief resident partnership or how to facilitate collaboration between the 2 roles, which collectively are important to program quality and resident satisfaction. We describe the development and impact of a novel workshop that paired program directors with their incoming chief residents to facilitate improved partnerships.

METHODS

The Accreditation Council for Graduate Medical Education sponsored a full-day workshop for residency program directors and their incoming chief residents. Sessions focused on increased understanding of personality styles, using experiential learning, and open communication between chief residents and program directors, related to feedback and expectations of each other. Participants completed an anonymous survey immediately after the workshop and again 8 months later to assess its long-term impact.

RESULTS

Participants found the workshop to be a valuable experience, with comments revealing common themes. Program directors and chief residents expect each other to act as a role model for the residents, be approachable and available, and to be transparent and fair in their decision-making processes; both groups wanted feedback on performance and clear expectations from each other for roles and responsibilities; and both groups identified the need to be innovative and supportive of changes in the program. Respondents to the follow-up survey reported that workshop participation improved their relationships with their co-chiefs and program directors.

CONCLUSION

Participation in this experiential workshop improved the working relationships between chief residents and program directors. The themes that were identified can be used to foster communication between incoming chief residents and residency directors and to develop a curriculum for chief resident development.

Getting to the heart of rectal bleeding: subacute bacterial endocarditis presenting as anaemia and a GI bleed

In this case report, the authors demonstrate a case of subacute bacterial endocarditis presenting with anaemia. It is the first of its kind to describe a delay in diagnosis due to an initial patient investigation for a bleed rather than a cardiac evaluation. Astute clinicians need to be aware of the causes of anaemia in patients with endocarditis and consider that in Streptococcus bovis (S bovis) infection can be related to gastrointestinal polyps or malignancy resulting in bleeding. Although patients with S bovis endocarditis should undergo full gastrointestinal investigation after endocarditis is diagnosed, it should not delay medical treatment. In this article, the authors discuss the consequences of failing to achieve timely recognition of endocarditis along with common systemic complications. The authors also outline current recommendations for surgical intervention as heart valve replacement surgery was warranted in the patient to prevent fatal outcome.

Postinfectious glomerulonephritis: Is there a role for steroids?

The role of steroids in treatment of postinfectious glomerulonephritis (PIGN) has been controversial. The reason for such controversy is the risk of infection relapse associated with steroid therapy. Steroids may have a place in the treatment of resistant cases where renal function does not improve despite aggressive antibiotic therapy as well as in patients with crescentic form of PIGN. We report a case of a 39 year-old Caucasian man who was diagnosed with methicillin-resistant Staphylococcus aureus (MRSA) bacteremia resulting in acute IgA dominant PIGN that failed to respond to antibiotic treatment alone, but responded significantly to steroids in addition to antibiotics. This anecdotal experience suggests that steroids could be considered in conjunction with antibiotic therapy for the treatment of refractory cases of PIGN or crescentic form of PIGN. More studies with long-term follow-up of patients treated with steroids in addition to antimicrobial agents are required to quantify the risk of infection relapse with steroid therapy.

Removal of hexavalent chromium by biosorption process in rotating packed bed

Removal of hexavalent chromium ions from an aqueous solution by crude tamarind (Tamarindus indica) fruit shell was examined in a rotating packed bed contactor by continuously recirculating a given volume of solution through the bed. Reduction of Cr(VI) to Cr(III) within the biosorbent appeared to be the removal mechanism. Depletion rate of Cr(VI) from, and release of reduced Cr(III) ions into the aqueous phase, was influenced by mass transfer resistance besides pH and packing depth. A mathematical model considering the reduction reaction to be irreversible and incorporating intraparticle and external phase mass transfer resistances represented the experimental data adequately. The study indicated that the limitations of fixed bed contactor operating under terrestrial gravity in intensifying mass transfer rates for this system can be overcome with rotating packed bed due to liquid flow under centrifugal acceleration.

A rare cause of seizure masquerading as neoplasm

The authors report the case of a young man with no significant medical history who presented with new-onset seizure and mass-like lesions isolated to the left cerebral hemisphere relating to malignancy. Biopsy revealed findings consistent with angiitis and investigations for secondary causes of angiitis was negative. The diagnosis of primary angiitis of the central nervous system was made and the patient has responded well to treatment.

An "education for life" requirement to promote lifelong learning in an internal medicine residency program

BACKGROUND

Lifelong learning is an integral component of practice-based learning and improvement. Physicians need to be lifelong learners to provide timely, efficient, and state-of-the-art patient care in an environment where knowledge, technology, and social requirements are rapidly changing.

OBJECTIVES

To assess graduates' self-reported perception of the usefulness of a residency program requirement to submit a narrative report describing their planned educational modalities for their future continued medical learning ("Education for Life" requirement), and to compare the modalities residents intended to use with their reported educational activities.

MATERIALS AND METHODS

Data was compiled from the Education for Life reports submitted by internal medicine residents at the University of Tennessee College of Medicine Chattanooga from 1998 to 2000, and from a survey sent to the same 27 graduates 2 to 4 years later from 2000 to 2004.

RESULTS

Twenty-four surveys (89%) were returned. Of the responding graduates, 58% (14/24) found the Education for Life requirement useful for their future continued medical learning. Graduates intended to keep up with a mean of 3.4 educational modalities, and they reported keeping up with 4.2. In a multivariable analysis, the number of modalities graduates used was significantly associated with the number they had planned to use before graduation (P  =  .04) but not with their career choice of subspecialization.

CONCLUSION

The majority of residents found the Education for Life requirement useful for their future continued medical learning. Graduates, regardless of specialty, reported using more modalities for continuing their medical education than they thought they would as residents. Considering lifelong learning early in training and then requiring residents to identify ways to practice lifelong learning as a requirement for graduation may be dispositive.

Primary pulmonary choriocarcinoma in a male

The authors report a case of a 48-year-old male smoker who presented with respiratory distress and constitutional symptoms along with gynaecomastia and multiple pulmonary nodules. Based on normal physical and ultrasound findings of the testes, presence of markedly elevated serum β human chorionic gonadotrophin (HCG) and biopsy findings of the lung a diagnosis of primary pulmonary choriocarcinoma was made.

Beer potomania: a case report

A syndrome of hyponatraemia associated with excessive beer drinking was first recognised in 1971. This syndrome has been referred to as beer potomania. Dilutional hyponatraemia occurs due to excessive consumption of an exclusive beer diet which is poor in salt and protein. We report a case of beer potomania who improved dramatically with introduction of solute load, with no subsequent neurological sequelae.

Do women residents delay childbearing due to perceived career threats?

PURPOSE

To assess gender differences among residents regarding their plans to have children during residency and determine the most influential reasons for these differences.

METHOD

Using the Health Belief Model as a framework, the authors created an instrument to survey 424 residents from 11 residency programs at three academic medical institutions about their intentions to have children during residency. The authors developed a scale to assess the perceived career threats of having children during residency, evaluated its psychometric properties, and calculated the effect of the mediators.

RESULTS

The response rate was 77% (328/424). Forty-one percent of men versus 27% of women planned to have children during residency (P = .01). The instrument measured four career threats-extended training, loss of fellowship positions, pregnancy complications, and interference with career plans-on a five-point Likert scale. The scale had a Cronbach alpha of 0.84 and an eigenvalue of 2.2. Compared with men, women had higher scores for each item and a higher mean score (2.9 versus 2.1, P = .001), signifying greater belief in the potential of pregnancy to threaten careers. After adjusting for age, institution, postgraduate year, and knowledge of parental leave policies, women were less likely to plan to have children during residency (odds ratio 0.46 [95% confidence interval 0.25-0.84]). In mediation analysis, threats to career explained 67% of the gender variance.

CONCLUSIONS

Women residents intentionally postpone pregnancy because of perceived threats to their careers. Medical educators should be aware of these findings when counseling female trainees.

Dural based mass: malignant or benign

In March 2007, a 68 year old female was diagnosed with colonic adenocarcinoma metastatic to the lungs and a frontoparietal parafalcine lesion suspected to be a meningioma was also noted. She denied neurologic symptoms and resection of the parafalcine lesion did not occur. For 14 months, she received chemotherapy with poor response. In June 2008, she developed multiple focal neurologic deficits. Enlargement of the parafalcine brain lesion was noted on head computerized tomography and magnetic resonance imaging. Cerebral angiogram demonstrated a parafalcine mass supplied by the middle meningeal artery. All 3 modality findings confirmed a meningioma. Embolization of the middle meningeal artery with craniotomy for excision of the suspected meningioma was performed. Pathology indicated metastatic adenocarcinoma with colonic primary without evidence of meningioma. Meningiomas are the most common dural based lesions; however, a variety of dural lesions mimic meningiomas. Dural metastatic tumors mimicking meningiomas is an uncommon phenomenon, particularly when the primary location is the colon. This paper additionally discusses the differentiation of benign dural based tumors like meningiomas from malignant findings. Multiple adjunct studies can differentiate meningiomas from metastatic tumor. The definitive diagnosis is based on histopathology.

Increased frequency and nocturia in a middle aged male may not always be due to Benign Prostatic Hypertrophy (BPH): a case report

Primary signet ring cell carcinoma of urinary bladder is a rare type of bladder tumor and carries a very high mortality rate. It may have a clinical presentation similar to common diseases like Benign Prostatic Hypertrophy (BPH) and the management options are extremely limited. We report a case of 58 year old Caucasian male who presented with a 5 month history of increased frequency of urination, nocturia and weight loss without any fever or hematuria. He was found to have an increased creatinine of 2.8 mg/dl and a prostate specific antigen level of 0.18 ng/ml. His azotemia was thought to be secondary to BPH. A foley catheter was initially placed with a plan for outpatient follow up. On removal of the catheter his problems persisted and he returned to the hospital. Diagnostic work up including abdominal ultrasonography, computed tomography (CT) scan, retrograde pyelogram, cystography and cystoscopic biopsies revealed the diagnosis of primary signet ring cell carcinoma of urinary bladder. Although cystectomy was planned, our patient passed away before this could be done.

[Relapse after surgical treatment of mycobacterium ulcerans infection (buruli ulcer): study of risk factors in 84 patients in the Democratic Republic of the Congo]

OBJECTIVE

To identify risk factors for relapse after exclusively surgical treatment of Mycobacterium ulcerans infection (Buruli ulcer).

METHODS

Study was carried out in 102 patients treated exclusively by surgery for Buruli ulcer at various care facilities in the Congo from January 1, 2000 to January 1, 2005.

RESULTS

Outcomes included relapse in 22 patients (21.5%), cure in 62 (60.7%), and unknown in 18 (17.6%). Statistical analysis identified the following variables as independent risk factors for relapse after exclusively surgical treatment: incomplete surgical excision (OR = 91.83; P = 0.0000; IC to 95%), age under 16 years (OR = 14.80; P = 0.0000; IC to 95%) and pre-ulcerative Buruli lesions (edema and plaque) (OR = 3.18; P = 0.0215; IC to 95%).

CONCLUSION

Quality of excision, patient age, and clinical form of lesion are the main predictors of relapse after isolated surgical treatment of Buruli ulcer.

Milk-alkali syndrome in a middle-aged woman after ingesting large doses of calcium carbonate: a case report

INTRODUCTION

Most cases of hypercalcaemia are secondary to malignancy or primary hyperparathyroidism. Here we report a case of hypercalcaemia that we have attributed to milk-alkali syndrome.

CASE PRESENTATION

A 51-year-old Caucasian woman with a past history of thyroidectomy and parathyroidectomy secondary to thyroid cancer developed an altered mental state and had an extremely high calcium concentration of 22.8 mg/dl (5.7 mmol/l). Investigations included work up for malignancy and hyperparathyroidism. However, the hypercalcaemia was attributed to ingestion of large doses of calcium carbonate, leading to milk-alkali syndrome. She was managed with intravenous fluids and withdrawal of calcium carbonate. The patient responded well to treatment, with normalization of the calcium concentration and clinical improvement.

CONCLUSION

We present this case to remind clinicians of the importance of detailed history taking and of milk-alkali syndrome as a cause of hypercalcemia.

Increased frequency and nocturia in a middle aged male may not always be due to benign prostatic hypertrophy: a case report

Primary signet ring cell carcinoma of urinary bladder is a rare type of bladder tumor and carries a very high mortality rate. It may have a clinical presentation similar to common diseases like benign prostatic hypertrophy and the management options are extremely limited. We report a case of 58-year-old Caucasian male who presented with a 5 month history of increased frequency of urination, nocturia and weight loss without any fever or hematuria. He was found to have an increased creatinine of 2.8 mg/dl and a prostate specific antigen level of 0.18 ng/ml. His azotemia was thought to be secondary to BPH. A Foley catheter was initially placed with a plan for outpatient follow up. On removal of the catheter his problems persisted and he returned to the hospital. Diagnostic work up including abdominal ultrasonography, computed tomography scan, retrograde pyelogram, cystography and cystoscopic biopsies revealed the diagnosis of primary signet ring cell carcinoma of urinary bladder. Although cystectomy was planned, our patient passed away before this could be done.

Achieving the AAAs of Ambulatory Care: Aptitude, Appeal, and Appreciation

BACKGROUND

In the current health care environment more patient care has moved from in-hospital care to the ambulatory primary care settings; however, fewer internal medicine residents are pursuing primary care careers. Barriers to residents developing a sense of competency and enjoyment in ambulatory medicine include the complexity of practice-based systems, patients with multiple chronic diseases, and the limited time that residents spend in the outpatient setting.

OBJECTIVE

In an effort to accelerate residents' ambulatory care competence and enhance their satisfaction with ambulatory practice, we sought to change the learning environment. Interns were provided a series of intensive, focused, ambulatory training sessions prior to beginning their own continuity clinic sessions. The sessions were designed to enable them to work confidently and effectively in their continuity clinic from the beginning of the internship year, and it was hoped this would have a positive impact on their perception of the desirability of ambulatory practice.

METHODS

Improvement needs assessment after a performance, so we developed a structured, competency-based, multidisciplinary curriculum for initiation into ambulatory practice. The curriculum focused on systems-based practice, patient safety, quality improvement, and collaborative work while emphasizing the importance of continuity of care and long-term doctor-patient relationships. Direct observation of patient encounters was done by an attending physician to evaluate communication and physical examination skills. Systems of care commonly used in the clinic were demonstrated. Resources for practice-based learning were used.

CONCLUSION

The immersion of interns in an intensive, hands-on experience using a structured ambulatory care orientation curriculum early in training may prepare the intern to be a successful provider and learner in the primary care ambulatory setting.

Band of cacophony - abdominal catastrophe caused by the fibrous band of Meckel's diverticulum: a case report

Introduction

This report calls attention to small bowel necrosis resulting as a complication of formation of an obstructive loop of small bowel around a band of Meckel's diverticulum.

Case presentation

We report a case of an adult in his 5th decade presenting with sharp, colicky abdominal pain. On presentation his vitals were within normal limits, abdomen was non-distended but tender and rigid all over, more on left lower quadrant without any rebound tenderness. Bowel sounds were hypoactive. Rectal exam showed an empty vault. White blood cell count was 9.0 x 103/mm3 with 94.5% neutrophils, Hb of 9.0 gm/dl and Hct of 31.3%, liver and pancreatic enzymes were not elevated. Arterial blood gas did not show any acidosis and lactic acid level was not elevated. X-ray showed a non-obstructive bowel pattern without any free air. Abdominal computed tomography with oral and intravenous gastrograffin showed findings consistent with complete mid to distal small bowel obstruction secondary to a closed loop obstruction. Emergent laparotomy showed a Meckel's diverticulum that had formed a band around a portion of small bowel causing it to twist upon itself and become necrotic.

Conclusion

Histopathology revealed Meckel's diverticulum and benign intestinal tissue with hemorrhagic necrosis.

A sore throat--potentially life-threatening?

A sore throat, which is most commonly viewed as a minor ailment, can be a manifestation of a life-threatening disorder known as Lemierre's syndrome caused by Fusobacterium necrophorum. We report a new case of Lemierre's syndrome that occurred in an otherwise healthy 18-year-old woman, who initially presented with fever and sore throat. The diagnosis was not made until a week later when blood cultures became available. This syndrome should be suspected until proven otherwise in any patient with signs of pharyngitis, a painful swollen neck, and pulmonary symptoms. By presenting this curable, but potentially life-threatening case of Lemierre's syndrome, we hope to increase the awareness of the early clinical manifestations of Lemierre's syndrome and to emphasize the importance of careful physical examination with special attention to the neck. Clinicians should be aware that exclusion of streptococcal infection in a patient with severe tonsillar infection does not exclude a bacterial cause.

Locked lung by looped hernia: a case report

Background

Large pleural effusions are usually symptomatic. We report a patient with asymptomatic massive left sided pleural effusion with left lung collapse secondary to a traumatic diaphragmatic hernia.

Case presentation

A 44 year old male presented with recurrent pleural effusions over six weeks. His pleural effusion was first diagnosed incidentally on a chest X-ray after a fall. Extensive diagnostic studies were unyielding for the etiology of the effusion. A diagnostic and therapeutic video assisted thoracoscopy revealed a diaphragmatic hernia with inflamed, incarcerated omentum. After hernia repair there was no recurrence.

Conclusion

This case underscores the obscure presentation of an incarcerated diaphragmatic hernia presenting as massive recurrent pleural effusions.

Limited Wegener's granulomatosis presenting as lung nodules in a patient with rheumatoid arthritis: a case report

Background

Rheumatoid arthritis has varied pleuroparenchymal manifestations. Wegener's granulomatosis can develop in an established case of rheumatoid arthritis and this association although previously reported is very rare.

Case presentation

A 60-year-old lady had been diagnosed with rheumatoid arthritis on the basis of her clinical symptoms and serological tests which were positive RA factor and anti-CCP antibodies. Her rheumatoid arthritis activity had been mild and well controlled with hydroxychloroquine and low dose prednisone. She presented with a productive cough and right-sided pleuritic chest pain. CT scan of the chest showed three lung nodules with increased uptake on PET CT scan, raising concerns for an inflammatory or malignant process. The differential diagnosis included rheumatoid nodules, infections or malignancy. A CT-guided needle biopsy of the largest nodule was undertaken which showed vasculitis typical of Wegener's granulomatosis. Stains and cultures of the biopsy specimen were negative for bacteria, fungi and acid fast bacilli. A panel of serological tests for vasculitis were checked and showed elevated titers of cANCA and anti-proteinase 3 antibodies. Urine analysis and CT scan of paranasal sinuses was normal. Since the upper respiratory tract and the kidneys were spared a diagnosis of limited Wegener's granulomatosis affecting only the lungs was made. Due to the toxicity of cyclophosphamide, her relatively mild disease sparing the kidneys and the underlying rheumatoid arthritis, weekly methotrexate was started and low dose prednisone was continued. She had marked symptomatic improvement and complete resolution of the nodules was documented on subsequent imaging.

Conclusion

Wegener's granulomatosis developing in a patient with rheumatoid arthritis is very rare but should be considered as it warrants a different and possibly more aggressive treatment approach.
